OSPF-EVPN

[zhangmazi123321]

Hello, I just started using FRR. I want to use EVPN between two virtual machines with different network segments, does EVPN support OSPF? Can you give some simple configuration examples? I can only find simple examples of BGP-EVPN. Or can you give some advice?

[ton31337]

No, no OSPF-EVPN support. Or what do you mean by OSPF EVPN? Underlay OSPF or what actually?

Hello! here is my config which i took from the official website. but i can't ping through exeс. I will be happy to help if you show me how to check the functionality.

show vrf vni -- gives two vrf. vni100 and vni200 and their mac addresses -- THIS OK.

show bgp l2vpn evpn - gives routes and hops -- THIS OK.

but -- show bgp summary -- gives : "up/dovn - never" hm.....

end ping with exec vrf - dont work... what is my problem?
