how to verify eBGP Load-sharing

Hi All

Two eBGP routers peer across two parallel serial links of equal bandwidth. I have configured loopback interface as an update source and eBGP-multihop on both routers.

Is here a way I could verify load-sharing is functioning accross the two parallel links?

Re: how to verify eBGP Load-sharing

Hi,

You mean you have RouterA and RouterB with two parallel serial links and you configured eBGP using loopback, static route each router loopback, and configure ebgp-multihop?

From RouterA traceroute loopback IP of RouterB. It should show two IP Address in the first hop. http://www.cisco.com/warp/public/459/40.html

Also, you can setup an MRTG to monitor it permanently.

In addition to the suggestion from Dandy I would suggest that one way to check might be to do show interface for both serial interfaces. If the packet count (inbound and outbound) is going up on both interfaces then it is proof of load sharing.
