Hi, We're a "regional" ISP in Cleveland and Akron, OH, and are in the process of adding 2x10Mb links out. The new uplink wants to peer between us and our current backbone, running BGP. Our current backbone told me that it would be difficult to get full BGP running on our router: a Cisco 7010. RAM is not a problem, we can bump it up to 64M in a moment's notice. Has anyone had problems running full routes on 7010s? Caveats? Things to look out for? Also, one newbie-type question, our current backbone said that they "may not" pass traffic routed via backbone #2. If I am running full BGP between both backbones, what would the technical limitations be of passing traffic between all three sites (Backbone A, Me, and Backbone B)? Any BGP gods out there for hire on a consultant basis? :-) TIA, -jamie -- jamie g. k. rishaw | jamie@arpa.com | jamie@multiverse.com url-free sig file | the religious right | Multiverse - the internet company corp: 216.771.0002 | is *neither*. | Multiverse - your internet company C4 48 1B 26 18 7B 1F D9 BA C4 9C 7A B1 07 07 E8 .. on a sesame - seed bun
Hi,

No problem. W/ 64mb you will have NO trouble speaking BGP and taking two full views on a 7010. You can have well over 20 BGP sessions pumping full routes without affecting the switching performance (esp. with an SSP). Filtering and IP tunneling and traffic shaping all take honking routers, and the 7010 might not have enough cpu for really complicated filtering on at high speed...
Has anyone had problems running full routes on 7010s? Caveats? Things to look out for?
No.
Also, one newbie-type question, our current backbone said that they "may not" pass traffic routed via backbone #2. If I am running full BGP between both backbones, what would the technical limitations be of passing traffic between all three sites (Backbone A, Me, and Backbone B)?
As long as they don't change their ASN, you just use AS-PATH filters.
Any BGP gods out there for hire on a consultant basis? :-)

All the ones I know of tend to be busy. This would be a good pointer for a Multihoming FAQ (interested consultants). Avi

We have some 7010s running as backbone routers, mainly for regional peering purposes. The 7010 is identical to 7000 in performance, just less slots.
Has anyone had problems running full routes on 7010s? Caveats? Things to look out for?
No problem. Problems seem to occur more on the 7000s since they normally have more cards and trunks attached and hence more likely to get loaded.

Just make sure you do not provide transit between two networks. Since they are your providers, the traffic may kill your links if they've got problems between their peerings/transits.
