Our setup consists of three routers A,B and C in an IPV6 network.
The routing protocol between A and B is ripng ipv6. The routing protocol
between B and C is iBGP ipv6.
We want B to advertise a route towards A with the next hop set to the
global IPV6 address of B. We are overriding the default behaviour of
setting the next hop as a link local address.
We have setup a next-hop routemap using the "set ipv6 next-hop global"
command. But we still see that the router is still advertising the next hop
with a link local address.
The configuration for Router B is shown below. (I have added [SNIP] as per
! Router B
router bgp 65521
! Router ID
bgp router-id 192.168.182.100
! Configure BGP_GW1 as iBGP peer
! Router C - IPV4
neighbor 192.168.182.98 remote-as 65521
neighbor 192.168.182.98 weight 1000
! Router C - 1PV6
neighbor 2001:[SNIP]:2eff:4182::98 remote-as 65521
neighbor 2001:[SNIP]:2eff:4182::98 route-map set-nexthop out
neighbor 2001:[SNIP]:2eff:4182::98 activate
! Route map to force the next hop to a global address
route-map set-nexthop permit 10
match ipv6 address all
set ipv6 next-hop global 2001:[SNIP]:2eff:4182::100
! Allow incoming Telnet connections
Thanks in advance,
