(ASCEND) OSPF
Once upon a time Phillip Vandry shaped the electrons to say...
>I heard some valid arguments recently against OSPF. Agreed that RIPv2 is
>probably no better (or worse), though.
Worse. It has all the drawbacks of RIP, except now it has VLSM/CIDR support.
Full routing updates, not just deltas, it is still distance vector, etc.
RIPv2 has been described as brain surgery on a dead patient. I worked with
the guy who developed RIPv2, back at Xylogics, great guy - but RIPv2 is
still a kludge to prolong the life of a dying patient.
>They were pushing EIGRP instead of OSPF (they were Cisco people). Obviously
>EIGRP is not an option for anyone who hasn't got a 100% Cisco network.
I wouldn't use EIGRP because it is proprietary - they'd love you to, because
it locks you into a Cisco network. I've never heard any strong arguments
to justify EIGRP over OSPF. Most Cisco users I know use the standards -
RIP, OSPF, BGP. Here, at GTEI/BBN, we're exclusively Cisco for routing -
and we use OSPF/BGP.
>The complaints against OSPF is that it forces you to have a network that is
>structured with a backbone area having the required properties of the
>OSPF backbone (zero) area, that is, every other area connects to it.
Yes - but this isn't as bad as it sounds. In practice this is rarely
noticable, and with forethought to design it is a non-issue. I've never
experienced any problems, myself or with a customer, getting this to work.
