MPLS - BGP: Spoke to Spoke Communication.

[bohra_ajay]

Hello All,

I'm having a problem with BGP in here. I'm unable to understand if it is AT MY END or the ISp (ISP is asking me to check at my end).

We have MPLS link from ISP and connecting our branch offices on it using Hub-Spoke Topology. ISP MPLS is terminating on WAN port at Branch and at HO. Till last month the Spoke Locations were connecting with each other, but now the traffic is ending at HUB and not passing through to the other spoke. I've not made any changes in the configuration at branch or at HO Routers.

I'm sharing the BGP Config at HUB and Spoke locations (IPs changed). Please suggest me any-thing that is required here.

Spoke -1

MNG# sh router bgp config router bgp set as 65535 set router-id XXX.XXX.XXX.XXX set synchronization enable config neighbor edit "XXX.XXX.XXX.XXX" set remote-as XXXX next end config network edit 1 set prefix 10.9.0.0 255.255.0.0 next end config redistribute "connected" set status enable end config redistribute "rip" end config redistribute "ospf" end config redistribute "static" end config redistribute "isis" end config redistribute6 "connected" end config redistribute6 "rip" end config redistribute6 "ospf" end config redistribute6 "static" end config redistribute6 "isis" end end

Spoke -2

KTK# sh router bgp config router bgp set as 64550 config neighbor edit "XXX.XXX.XXX.XXX" set remote-as XXXX set send-community6 disable next end config redistribute "connected" set status enable end config redistribute "rip" end config redistribute "ospf" end config redistribute "static" end config redistribute "isis" end config redistribute6 "connected" end config redistribute6 "rip" end config redistribute6 "ospf" end config redistribute6 "static" end config redistribute6 "isis" end end

HUB (HO_OFFICE)

HO_HUB_IND~ # sh router bgp config router bgp     set as 65526         config neighbor             edit "XXX.XXX.XXX.XXX"                 set capability-default-originate enable                 set soft-reconfiguration enable                 set remote-as XXXX                 set send-community6 disable                 set keep-alive-timer 10                 set holdtime-timer 30                 set weight 65534             next         end         config network             edit 2                 set prefix 10.7.0.0 255.255.0.0             next             edit 3                 set prefix 10.17.40.0 255.255.254.0             next             edit 4                 set prefix 10.14.0.0 255.255.0.0             next             edit 6                 set prefix 172.16.15.160 255.255.255.224             next         end         config redistribute "connected"             set status enable         end         config redistribute "rip"         end         config redistribute "ospf"         end         config redistribute "static"             set status enable         end         config redistribute "isis"         end         config redistribute6 "connected"         end         config redistribute6 "rip"         end         config redistribute6 "ospf"         end         config redistribute6 "static"         end         config redistribute6 "isis"         end     set router-id XXX.XXX.XXX.XXX end

Since you 'X'-outed neighbor config, I can't see the topology of the BGP network. Is the neighbor of spokes the HUB/HO? Or the MPLS provider is actually the hub to connect all locations both HO and branches over BGP?
