I use OSPF network to create BGP. I use router3 to server also as the BGP router.

I enabled BGP on router3, added interface. On Dom0 added eth1 as bridge, on DomU added br0 as bridge and edited the port accordingly.

But cannot reach any of the other addresses.

I peer with Hidde (172.16.0.17) and he provides transit for me and Roy (172.16.0.14). I can ping there machine 10.17.1.1 for Hidde and 10.14.1.1 for Roy. And they can also ping mine (10.13.0.1).

I defined max allowed prefixes per peer to 10, it should be enough for this lab. And redistribute OSPF to BGP, however Hidde is not accepting it, so I have to look for other peers who are willing to share more detailed information ;)

So ping me on <hi #ff00ff>10.13.0.1</hi>, and open for peer!!!

After several days of head scratching, it turns out to be the IX switch which is splitting us into several groups. Switch to other ports appear to be in one group. Problem solved!!
