RE: About BGP [7:26353]
Hi, Try connecting both the routers using two different hubs/switches ie., avoid connecting them through a single switch/hub, no mater if you have them on different subnets. I had the same problem while dong my bgp lab at my ccnp days. I used a single switch but created 2 VLANs on it. It worked for me. thanks Suresh MCSE+I,CNE,CCSA,SCSA,CCSA,MCNS,CCNP,CCIE(Write) http://www.sureshhomepage.com >From: "[EMAIL PROTECTED]" >Reply-To: "[EMAIL PROTECTED]" >To: [EMAIL PROTECTED] >Subject: RE: about BGP [7:26353] >Date: Thu, 15 Nov 2001 15:44:09 -0500 > >Did you configure ebgp-multihop? > >-Original Message- >From: ]hsan Turkmen [mailto:[EMAIL PROTECTED]] >Sent: Thursday, November 15, 2001 1:37 PM >To: [EMAIL PROTECTED] >Subject: about BGP [7:26353] > > >Hi. > >I am trying to configure two routers as BGP peers .

RE: about BGP [7:26353]
BGP rides on top of TCP and BGP's default TTL is 1. Therefore to run BGP you must be directly connected, unless you implement ebgp multi-hop. Which allows you to reconfigure BGP's TTL value so that you may establish a BGP session with that neighbor that is not directly connected. HTH, Chris Christopher A.

You need to use bgp multihop if there is a hop in between... -- -=Repy to group only... no personal=- ""]hsan Turkmen"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hi. > > I am trying to configure two routers as BGP peers .

RE: about BGP [7:26353]
To Configure BGP on Non-directly connected neighbors, you use the following command Router bgp AS neigbor X.X.X.X ebgp-multihop N Where: AS is your AS number X.X.X.X is the Ip address of the remote Peer N is the maximum number of hops between the 2 peers (N is reccomended but not required.)
