Re: BGP with ip6

Most providers will do two separate peering sessions for IPv4 and IPv6. You can request a single one, but each provider will have their own policy for this.

Re: Prepend vs. Local Pref

You would need to use both techniques. Prepending your AS on the outgoing filters makes it less preferrable for other ISP's to send traffic through that particular link because you're "tricking" them into thinking that there is more AS's in the way. Since BGP uses the least amount of AS's to cross i...

Re: BGP w/ Cogent

Since they are in so many buildings, it also allows them to only run full BGP routing on certain key locations. Most of their access switches aren't carrier routers, but rather BGP enabled switches that bring the routes back to the core. The second peer is a "Multihop" peer. In some cases it can be ...

High CPU with IPv6 BGP on v4.17

Testing a BGP tunnel with Hurricane Electric on a RB1100AH (6to4 interface), receiving approx 6500 routes, running v4.17. CPU is 100% even after accepting all the routes. As soon as I take the peer down, CPU goes back to 0. This doesn't happen if you discard all routes and set a manual default. Any ...

Re: BGP w/ Cogent

Why are you using loopbacks for eBGP between providers (loopbacks are typically used in iBGP configuration)? +1 That doesn't make much sense. It only makes sense when you're using an IGP to manage multiple links between the routers which would cause the source IP to change when the main link goes d...

Why don't you just drop all traffic to their network?

Create an address list with all of those prefixes and drop the traffic in a firewall rule.

Re: Memory Leak with BGP?

Curious if anyone that are using RB1000U's have actually switched from the default RAM.

I have a RB1000 running BGP with 2 peers and the default (512mb) of RAM and ROS 4.5. And I cannot confirm any graphs that look like the above.

I'm only holding about 100k routes at this point though.

Re: Will RB1000U Handle 2-3 BGP Sessions

Depends on the number of routes. If you want three feeds with full routes you should go to 1.5GB RAM. If you're just getting defaults and announcing a few blocks of your own, it'll do fine with the stock RAM.
Do you think it will handle 2 with sessions with full routes?

There's many ways to approach that. You could create a script and copy/paste it in, or upload it and import the script.
