Excerpt: I was inspired by a (relatively) recent post by Jeremy Stretch at Packetlife.net that explained OSPF designated router configuration in Cisco IOS. I’d like to go into a bit more detail regarding the need for a designated router, and explore the same configuration steps on the Vyatta Core platform. I’ve already shown how easy it is to integrate a Cisco router with a Vyatta router using OSPF, so you can use a mix of Cisco and Vyatta gear if you wish. To understand the purpose of a Designated Router in OSPF, you need to know how OSPF distributes routing information around the…

I used the guide here to bridge both virtual routers together, so that communication could be established. The Cisco side was pretty straightforward. I configured the FastEthernet interface and enabled OSPF on it: R1#(config)interface Fa0/0 R1#(config-int)ip addr 172.16.0.1 255.255.255.0 R1#(config-int)no shut R1#(config-int)exit R1#(config)router ospf 1 R1#(config-router)router-id 1.1.1.1 R1#(config-router)network 172.16.0.1 0.0.0.0 area 0 The Vyatta side took some doing, though there were more interfaces involved here, so that could be…
