I am trying this configuration where the Blue and Red routers are acting as hosts.
I can make the Blues talk with the Blues and the Reds talk with the Reds. Now I want Red1 to talk with Blue1 but only via CiscoIOSv-2.
I have installed default routes at CiscoIOSv-1 that show up at the respective VRF routing tables using the commands:
ip route vrf blue 0.0.0.0 0.0.0.0 184.108.40.206 global ip route vrf red 0.0.0.0 0.0.0.0 220.127.116.11 global
My problem is that when I ping from Blue1 to Red1 the ICMP packets do not carry a Blue tag in the provider’s network. Only when I ping from Blue1 to Blue2 they do. It seems that CiscoIOSv-1 is ignoring the association between the default route and the Blue Route Tag. Any idea of what is wrong?
The BGP configuration of CiscoIOSv-1 is:
router bgp 100 neighbor 18.104.22.168 remote-as 100 neighbor 22.214.171.124 update-source Loopback0 address-family vpnv4 neighbor 126.96.36.199 activate exit address-family ipv4 vrf blue redistribute connected exit address-family ipv4 vrf red redistribute connected
and the configuration of the VRFs is:
ip vrf blue rd 1:1 route-target both 1:1 ip vrf red rd 2:2 route-target both 2:2
