BGP route issue

Unanswered Question

I have two sites connect to an MPLS network through two different POPS  POP C and POP D


Site A redistributes a static route pointing to a vendor router at that location

Site B redistributes a static route pointing to a vendor router at that location.


Both routes are for the same network.


Site A example   192.168.1.1  255.255.255.0 is routing to 192.168.2.1  (connects to POP C)

Site B example   192.168.1.1 255.255.255.0 is routing to 192.168.3.1  (connects to POP D)


After temporary shutdown of Site B, all locations have Site A static route.


We believe that sites connecting to POP C should route to Site A  and sites connecting to POP D should route to Site B


How do  I get site that connect to POP D route to site B?


Hope this makes sense


Thanks

Hello Thom,


what kind of service are you getting?


a L3 MPLS VPN or a L2 VPN ?


Do your routers peer with service provider PE nodes or directly between themselves?


If it is a L2 MPLS VPN you just need to use local preference to have site C to prefer site A route and site D to prefer site B route.


If it is a L3 MPLS VPN it is still possible but you need to use BGP communities and you need to cooperate with service provider.



Hope to help

Giuseppe
