yeah that's right i can't ping H2 from H0 but H0 know only H1 it didn't try to reach H2 indeed when i try to ping H1.eth1 from H0.eth1 it works. this nitht i will modify my program to have different networks an i will notify you if it works. Another question, when it will be implemented Aggregatio

Re: Bgp 4 peer problems, 2 peer stay in connect

Hello, as Ondrej mentioned already, you have wrong basic network setup - you're using wrong network masks. H0 thinks, that all nodes (H1, H2, H3) ale in single directly-connected L2 network. To have BGP working, you need to have basic L3 connectivity working - that means, you must be able to ping

all external interface of the peer belong to the same network, and the address of the network is 10.0.0.0/8 that is unic. sorry for the network picture, i noted after had sended the email that it get mangled. now i try to explain it more clearly H0 belong to AS2 and have the interface eth1 with t

and sorry there is a way to specify the interface? if I use "interface *;" (replace star with the host interface to use for the BGP protocol conf) it give me the message that there is an error in the line of interface spec. 2018-03-07 16:45 GMT+01:00 Mattia Milani : > yeah they are a /8, so
