By default, a device does not use a
default route to resolve a BGP4+ next-hop route.
About this task
If the IPv6 route lookup for the BGP4+
next-hop does not result in a valid Interior Gateway Protocol (IGP) route (including
static or direct routes), the BGP4+ next-hop is considered to be unreachable and the
BGP4+ route is not used. You can configure the device to use the default route as a
valid next hop.
Procedure
-
Access global configuration
mode.
device# configure terminal
-
Access BGP configuration mode.
device(config)# router bgp
-
Access IPv6 address family
configuration mode.
device(config-bgp-router)# address-family ipv6 unicast
-
Configure the device to use the
default route as a valid next hop.
device(config-bgp-ipv6u)# next-hop-enable-default
Example
The following example summarizes the commands in
this procedure.
device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# next-hop-enable-default
