Service Provider Route Reflectors and Client for iBGP IPv4

Use Case

In large service provider networks it is necessary to divide the routing functionality into two or more layers: a backbone layer and a gateway layer. This allows backbone routers to be focused on core routing and switching to/from other areas of the routing domain, and gateway routers may then be focused on interconnecting other service provider customers.

Example Scenario

In this example, the service provider will have a fictitious autonomous system number (ASN) of 65505, Each network POP, of which only one will be detailed here, will feature 2 backbone routers which will be configured as route-reflectors. These backbone routers will be participating in BGP Cluster ID 100. Other POPs will likely be different Cluster IDs.

There will also be a single gateway router which will be a client of the backbone route-reflectors. Of course, in real world scenarios there would likely be many more gateway routers, each serving a full complement of customers.

rr2 tnsr(config-interface)# ip address 203.0.113.17/30
rr2 tnsr(config-interface)# enable
rr2 tnsr(config-interface)# exit
rr2 tnsr(config)# interface GigabitEthernet0/14/0
rr2 tnsr(config-interface)# description "To RR1 Router"
rr2 tnsr(config-interface)# ip address 203.0.113.22/30
rr2 tnsr(config-interface)# enable
rr2 tnsr(config-interface)# exit
rr2 tnsr(config)# interface GigabitEthernet0/15/0
rr2 tnsr(config-interface)# description "To GW router"
rr2 tnsr(config-interface)# ip address 203.0.113.9/30
rr2 tnsr(config-interface)# enable
rr2 tnsr(config-interface)# exit
rr2 tnsr(config)#

GW:

gw tnsr# conf
gw tnsr(config)# interface GigabitEthernet0/13/0
gw tnsr(config-interface)# description "To RR1 Router"
gw tnsr(config-interface)# ip address 203.0.113.6/30
gw tnsr(config-interface)# enable
gw tnsr(config-interface)# exit
gw tnsr(config)# interface GigabitEthernet0/14/0
gw tnsr(config-interface)# description "To RR2 Router"
gw tnsr(config-interface)# ip address 203.0.113.10/30

gw tnsr(config)# interface GigabitEthernet0/15/0
gw tnsr(config-interface)# desc "To Customer Router"
gw tnsr(config-interface)# ip address 203.0.113.25/30
gw tnsr(config-interface)# enable
gw tnsr(config-interface)# exit
gw tnsr(config)#

Step 2: Enable BGP

RR1:

rr1 tnsr(config)# route dynamic bgp
rr1 tnsr(config-frr-bgp)# enable
rr1 tnsr(config-frr-bgp)# exit
rr1 tnsr(config)#

RR2:

rr2 tnsr(config)# route dynamic bgp
rr2 tnsr(config-frr-bgp)# enable
rr2 tnsr(config-frr-bgp)# exit
rr2 tnsr(config)#

GW:

gw tnsr(config)# route dynamic bgp
gw tnsr(config-frr-bgp)# enable
gw tnsr(config-frr-bgp)# exit
gw tnsr(config)#

Step 3: Create prefix-lists for route import into BGP on Route-Reflectors

RR1:

rr1 tnsr(config)# route dynamic prefix-list REDISTRIBUTE_IPv4
rr1 tnsr(config-prefix-list)# description "IPv4 Routes to Import"
rr1 tnsr(config-prefix-list)# seq 10 permit 192.0.2.0/24
rr1 tnsr(config-prefix-list)# seq 20 permit 203.0.113.0/24
rr1 tnsr(config-prefix-list)# exit
rr1 tnsr(config)#

RR2:

rr2 tnsr(config)# route dynamic prefix-list REDISTRIBUTE_IPv4
rr2 tnsr(config-prefix-list)# description "IPv4 Routes to Import"
rr2 tnsr(config-prefix-list)# seq 10 permit 192.0.2.0/24
rr2 tnsr(config-prefix-list)# seq 20 permit 203.0.113.0/24
rr2 tnsr(config-prefix-list)# exit
rr2 tnsr(config)#

Step 4: Create route-map for route import into iBGP on route-reflectors

RR1:

rr1 tnsr(config)# route dynamic route-map REDISTRIBUTE_IPv4 permit sequence 10
rr1 tnsr(config-route-map)# match ip address prefix-list REDISTRIBUTE_IPv4
rr1 tnsr(config-route-map)# set origin igp
rr1 tnsr(config-route-map)# exit
rr1 tnsr(config)#

RR2:

rr2 tnsr(config)# route dynamic route-map REDISTRIBUTE_IPv4 permit sequence 10
rr2 tnsr(config-route-map)# match ip address prefix-list REDISTRIBUTE_IPv4
rr2 tnsr(config-route-map)# set origin igp
rr2 tnsr(config-route-map)# exit
rr2 tnsr(config)#

Step 5: Create static route for networks to be advertised in BGP

RR1:

rr1 tnsr(config)# route ipv4 table ipv4-VRF:0
rr1 tnsr(config-route-table-v4)# route 192.0.2.0/24
rr1 tnsr(config-rttbl4-next-hop)# next-hop 1 via local
rr1 tnsr(config-rttbl4-next-hop)# exit
rr1 tnsr(config-route-table-v4)# route 203.0.113.0/24
rr1 tnsr(config-rttbl4-next-hop)# next-hop 1 via local
rr1 tnsr(config-rttbl4-next-hop)# exit
rr1 tnsr(config-route-table-v4)# exit
rr1 tnsr(config)#

RR2:

rr2 tnsr(config)# route ipv4 table ipv4-VRF:0
rr2 tnsr(config-route-table-v4)# route 192.0.2.0/24
rr2 tnsr(config-rttbl4-next-hop)# next-hop 1 via local
rr2 tnsr(config-rttbl4-next-hop)# exit
rr2 tnsr(config-route-table-v4)# route 203.0.113.0/24
rr2 tnsr(config-rttbl4-next-hop)# next-hop 1 via local
rr2 tnsr(config-rttbl4-next-hop)# exit
rr2 tnsr(config-route-table-v4)# exit
rr2 tnsr(config)#

Step 6: Configure BGP global options

RR1:

rr1 tnsr(config)# route dynamic bgp
rr1 (config-frr-bgp)# server 65505
rr1 tnsr(config-bgp)# router-id 203.0.113.21
rr1 tnsr(config-bgp)# cluster-id 100
rr1 tnsr(config-bgp)# address-family ipv4 unicast
rr1 tnsr(config-bgp-ip4uni)# redistribute kernel route-map REDISTRIBUTE_IPv4
rr1 tnsr(config-bgp-ip4uni)# exit
rr1 tnsr(config-bgp)#

RR2:

rr1 tnsr(config)# route dynamic bgp
rr1 (config-frr-bgp)# server 65505
rr2 tnsr(config-bgp)# router-id 203.0.113.22
rr2 tnsr(config-bgp)# cluster-id 100
rr2 tnsr(config-bgp)# address-family ipv4 unicast
rr2 tnsr(config-bgp-ip4uni)# redistribute kernel route-map REDISTRIBUTE_IPv4
rr2 tnsr(config-bgp-ip4uni)# exit
rr2 tnsr(config-bgp)#

GW:

gw tnsr(config)# route dynamic bgp
gw (config-frr-bgp)# server 65505
gw tnsr(config-bgp)# router-id 203.0.113.6
gw tnsr(config-bgp)#

Step 7: Configure iBGP peer-group for backbone route-reflectors and add neighbor

RR1:

rr1 tnsr(config-bgp)# neighbor iBGP
rr1 tnsr(config-bgp-neighbor)# remote-as 65505
rr1 tnsr(config-bgp-neighbor)# description "iBGP Sessions"
rr1 tnsr(config-bgp-neighbor)# update-source GigabitEthernet0/14/0
rr1 tnsr(config-bgp-neighbor)# enable
rr1 tnsr(config-bgp-neighbor)# exit
rr1 tnsr(config-bgp)# neighbor 203.0.113.22
rr1 tnsr(config-bgp-neighbor)# peer-group iBGP
rr1 tnsr(config-bgp-neighbor)# enable
rr1 tnsr(config-bgp-neighbor)# exit

RR2:

rr2 tnsr(config-bgp)# neighbor iBGP
rr2 tnsr(config-bgp-neighbor)# remote-as 65505
rr2 tnsr(config-bgp-neighbor)# description "iBGP Sessions"
rr2 tnsr(config-bgp-neighbor)# update-source GigabitEthernet0/14/0
rr2 tnsr(config-bgp-neighbor)# enable
rr2 tnsr(config-bgp-neighbor)# exit
rr2 tnsr(config-bgp)# neighbor 203.0.113.21
rr2 tnsr(config-bgp-neighbor)# peer-group iBGP
rr2 tnsr(config-bgp-neighbor)# enable
rr2 tnsr(config-bgp-neighbor)# exit

Step 8: Configure RR-CLIENT peer-group for route-reflector clients and add neighbor

RR1:

rr1 tnsr(config-bgp)# neighbor RR-CLIENT
rr1 tnsr(config-bgp-neighbor)# remote-as 65505
rr1 tnsr(config-bgp-neighbor)# description "RR-Client Sessions"
rr1 tnsr(config-bgp-neighbor)# update-source GigabitEthernet0/15/0
rr1 tnsr(config-bgp-neighbor)# enable
rr1 tnsr(config-bgp-neighbor)# exit
rr1 tnsr(config-bgp)# neighbor 203.0.113.6
rr1 tnsr(config-bgp-neighbor)# peer-group RR-CLIENT
rr1 tnsr(config-bgp-neighbor)# enable
rr1 tnsr(config-bgp-neighbor)# exit
rr1 tnsr(config-bgp)#

RR2:

rr2 tnsr(config-bgp)# neighbor RR-CLIENT
rr2 tnsr(config-bgp-neighbor)# remote-as 65505
rr2 tnsr(config-bgp-neighbor)# description "RR-Client Sessions"
rr2 tnsr(config-bgp-neighbor)# update-source GigabitEthernet0/15/0
rr2 tnsr(config-bgp-neighbor)# enable
rr2 tnsr(config-bgp-neighbor)# exit
rr2 tnsr(config-bgp)# neighbor 203.0.113.10
rr2 tnsr(config-bgp-neighbor)# peer-group RR-CLIENT
rr2 tnsr(config-bgp-neighbor)# enable
rr2 tnsr(config-bgp-neighbor)# exit
rr2 tnsr(config-bgp)#

Step 9: Configure both peer-group address-family options on route-reflectors

RR1:

rr1 tnsr(config-bgp)# address-family ipv4 unicast
rr1 tnsr(config-bgp-ip4uni)# neighbor iBGP
rr1 tnsr(config-bgp-ip4uni-nbr)# next-hop-self
rr1 tnsr(config-bgp-ip4uni-nbr)# activate
rr1 tnsr(config-bgp-ip4uni-nbr)# exit
rr1 tnsr(config-bgp-ip4uni)# neighbor RR-CLIENT
rr1 tnsr(config-bgp-ip4uni-nbr)# route-reflector-client
rr1 tnsr(config-bgp-ip4uni-nbr)# activate
rr1 tnsr(config-bgp-ip4uni-nbr)# exit
rr1 tnsr(config-bgp-ip4uni)# exit
rr1 tnsr(config-bgp)#

RR2:

rr2 tnsr(config-bgp)# address-family ipv4 unicast
rr2 tnsr(config-bgp-ip4uni)# neighbor iBGP
rr2 tnsr(config-bgp-ip4uni-nbr)# next-hop-self
rr2 tnsr(config-bgp-ip4uni-nbr)# activate
rr2 tnsr(config-bgp-ip4uni-nbr)# exit
rr2 tnsr(config-bgp-ip4uni)# neighbor RR-CLIENT
rr2 tnsr(config-bgp-ip4uni-nbr)# route-reflector-client
rr2 tnsr(config-bgp-ip4uni-nbr)# activate
rr2 tnsr(config-bgp-ip4uni-nbr)# exit
rr2 tnsr(config-bgp-ip4uni)# exit
rr2 tnsr(config-bgp)#

Step 10: Configure iBGP on gateway router to both route-reflectors

GW:

gw tnsr(config-bgp)# neighbor 203.0.113.5
gw tnsr(config-bgp-neighbor)# remote-as 65505
gw tnsr(config-bgp-neighbor)# description "RR1 Session"
gw tnsr(config-bgp-neighbor)# update-source GigabitEthernet0/13/0
gw tnsr(config-bgp-neighbor)# enable
gw tnsr(config-bgp-neighbor)# exit
gw tnsr(config-bgp)# neighbor 203.0.113.9
gw tnsr(config-bgp-neighbor)# remote-as 65505
gw tnsr(config-bgp-neighbor)# description "RR2 Session"
gw tnsr(config-bgp-neighbor)# update-source GigabitEthernet0/14/0
gw tnsr(config-bgp-neighbor)# enable
gw tnsr(config-bgp-neighbor)# exit
gw tnsr(config-bgp)# address-family ipv4 unicast
gw tnsr(config-bgp-ip4uni)# neighbor 203.0.113.5
gw tnsr(config-bgp-ip4uni-nbr)# activate
gw tnsr(config-bgp-ip4uni-nbr)# exit
gw tnsr(config-bgp-ip4uni)# neighbor 203.0.113.9
gw tnsr(config-bgp-ip4uni-nbr)# activate
gw tnsr(config-bgp-ip4uni-nbr)# exit
gw tnsr(config-bgp-ip4uni)# exit
gw tnsr(config-bgp)#
