BGP

Dear All,

We are using BGP (MPLS) for all the Branches. Several branches links were down; also we have Backup for all the Branches. When Links were down at the time Backup also not coming UP. Branches were totally isolated. After Restored the links I checked the BGP Status on one of the Branch

Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxR

10.xx.xx.xx 4 9829 1494835 173642 4 0 0 1d05h 0

By seeing Summary BGP was Not Fluctuvated.not only this Branch I checked all the Branches which are down .there also BGP was not Flapping. How it's Possible and what could be a reason.

Re: BGP

hi,

as per the provided output of sh ip bg sum,

you can see that at last digit of the summary i.e. 0 means you are not receiving any prefixes at your branches.

pls confirm that, is this true?

thanks and regards,

sourabh

Re: BGP

Hi,

Prefix list has been configured in Branch Routers that's why it's not receiving.
