thank you but I was probably to vague in my qiestion. I understand how to see BGP neighbors and view BGP routes in the routing table I was more concerned with being able to verify that I was getting all the routes from my ISP. Now that I look at it more closely I am not sure there is any way other than seeing the total route counts and if it is in 100K+ range assume I am getting all internet routes.

thanks

In fact, it's more in the 250K+ range than in the 100K. If you only have ~100K routes, you are missing more than half the internet.

I think your provider is feeding your router with "customer routes", i.e., its own routes plus their clients'.

Hello,

You can use the "sh ip bgp sum" command to view quickly an approximate total number of routes received from your ISP.

Sample output:

...

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

4 1618700 129642 11697332 0 0 2w6d 265990

...

The value under the "State/PfxRcd" column shows how many prefixes you have received over an established session with your peer (~265990 now).

Check out the website: http://bgp.potaroo.net/ for current status of the Internet Routing Table.
