Default RouteΒΆ
In TNSR, the default route, sometimes called a default gateway,
is the gateway of last resort.
Meaning, traffic that is not local and does not have any other
route specified will be sent using that route.
There is no default
keyword in TNSR;
Instead, the special network 0.0.0.0/0
is used for IPv4 and ::/0
is used
for IPv6.
In this example, the gateway from Example Configuration is added using the WAN interface:
IPv4 Default Route Example:
tnsr(config)# route table ipv4-VRF:0
tnsr(config-route-table)# route 0.0.0.0/0
tnsr(config-rttbl4-next-hop)# next-hop 0 via 203.0.113.1
tnsr(config-rttbl4-next-hop)# exit
tnsr(config-route-table)# exit
IPv6 Default Route Example:
tnsr(config)# route table ipv6-VRF:0
tnsr(config-route-table)# route ::/0
tnsr(config-rttbl6-next-hop)# next-hop 0 via 2001:db8:0:2::1
tnsr(config-rttbl6-next-hop)# exit
tnsr(config-route-table)# exit
