BGP prefix and routing
Dear Experts,
Can any one throw some light as one of our collegue who configured this left without proper KT and we are trying sort the routing issue here. We have limited knowledge on routing prefix under bgp routing. We have our route information showing up as below
we have publish /23 subnet on two different carriers. Now we have two issues
1. There is a default route 0.0.0.0/0 added in our bgp router from upstream router. We need to stop this since all our uplink traffic from all bgp carriers and non bgp carrier traffic is being routed through one second bgp published carrier rather than by our rule set
2. We did not completely understand what does below prefix rules means. We need traffic to be load balanced between two bgp published carrier links while prevent the carrier to push the routing 0.0.0.0/0 to our bgp router
we tried to take help of carrier with no luck..
Can someone throw some light on below since we do not have much time otherwise we can google study and fix it
bgp# show running-config
Current configuration:
!
hostname bgp
log stdout
!
router bgp 2026xx
bgp router-id 83.111.x.x
network 91.72.x.x/25
network 185.151.x.0/23
neighbor 83.111.134.x rem
neighbor 87.201.148.x rem
!
ip prefix-list ABC seq 10
ip prefix-list ABC seq 20
ip prefix-list Block_route
!
route-map Block-default pe
match ip address prefix-l
!
route-map Block-default pe
