RE: BGP quandary
Title: RE: BGP quandary
I do not claim to be a BGP guru but here is my take. If my take is way of base I would like to here from our BGP guru's here
This may be an obvious answer, but, like some obvious answers, you just
I have four routers in a network. Two of the routers have no external
p1(e) p2(e) p1(e) p2(e)
p1 (AS12345) and p2 (AS12346) are the same AS across both routers, but
!# This is a bit confusing to me p1(AS12345) is p1 no matter what rtr connects to it or where it connects. Same goes for p2(As12346).
My quandary is this: I want to advertise my best path to swr_1 and swr_2.
!# This may be difficult to do if you want any type of redundant pathing. Both swr's will need a peering session (tcp connection) to both rtr's for redundancy(unless you don't care). Therefore I would suggest iGBP peering betwween the rtr's and swr's and not worry about the swr's making a decision. You can use dampening if you are worried about excessive cpu utilization.
further complicating the issue, swr_1 and swr_2 have to accomplish the same
!# The only way to get one "best path" pushed is to have only one peer, igrp or egrp or default route to the eBGP rtr. Ohterwise the routing protocol will make a decision on what route to inject into it's table based on the metric if more than one is recieved.
the fw device will route to the swr devices, probably via HSRP, but if they
I can see several options, all of which have significant disadvantages and
does anyone have any suggestions on how to solve this situation?
