In my lab, I have 2P, 2 PE and 2 CE and try to build mpls vpn cloud.
I want to use BGP as a routing between PE-CE.
CE-A ------- PE-A ------ P ---- P ------ PE-B ----CE-B
router bgp 65000
address-family ipv4 vrf V79:vpntest
neighbor 10.10.10.1 remote-as 65499
neighbor 10.10.10.1 update-source Serial3/0
neighbor 10.10.10.1 activate
router bgp 65499
network 10.10.10.2 mask 255.255.255.255
neighbor 10.10.10.2 remote-as 65000
neighbor 10.10.10.2 update-source Serial2/0
The issue is :
1) In CE-B when I show ip route, it doesn't display route that coming from CE-A ie loopback IP, FE IP etc although PE-B have the route. What do i need to configure if I want CE-B receive the route. The reason why I need to have the routes is for ISDN back-up between CE to CE
It works. I need to improve my bgp knowledge from now on :)
Now I have complete solutions for my network.
For fine-tuning, when primary LL down, there were 23 packets loss before ISDN start to kick-off and routing fully converges and took only 3 packets loss from ISDN to primary after LL is up. I'try not to change any default value on BGP, but the if anyone have a suggestion, you are most welcome to share with me and us as well.
