OSPF MD5 and IOS 12.0.7

I am trying to have OSPF with MD5 on a fastethernet segment. Chasis type is

CS2621, IOS is c2600-is-mz.120-7.T.

Config looks something like:


interface FastEthernet0/1

ip ospf authentication message-digest

ip ospf message-digest-key 1 md5 0 <password>

I can see neigborship over fastethernet segment but it looks like router is NOT usign MD5 for this!!!

When doing a 'sh ip o int', I do not see something like :


Message digest authentication enabled

Youngest key id is 1

Is there a bug with IOS 12.0.7 ?

With IOS 12.1.13, I can see this without problem...

Thanx in advance. Mihai

Re: OSPF MD5 and IOS 12.0.7

It looks like the MD5 is NOT used, as already written...

Dec 4 14:05:15 UTC: OSPF: Rcv hello from area 0 from FastEthernet0/1

Dec 4 14:05:15 UTC: OSPF: End of hello processing

My feeling is that this is a bug. I have deleted the lines, re-inserted, still nothing...

Re: OSPF MD5 and IOS 12.0.7

Could it be that 12.0.7 does NOT support MD5 authentication on a segment ONLY as more recent IOS do??? I have NOT configured it on the entire area...

Re: OSPF MD5 and IOS 12.0.7

You need to configure authentication in that area, using

area authentication message-digest
