Another issue with the scaling of LSAs and LSPs concerns the ability of link ... When there is a low-MTU link along the flooding path, an OSPF or IS-IS implementation can do one of three things: It ca... read more

EIGRP vs OSPF – Take 2

I mean where are the “ISIS vs OSPF” debates ... Conversely, the as the number of nodes (routers) grow in a network, the work OSPF has to do increases, forcing more OSPF areas so it can scale to, forci... read more
