Re: [mpls-linux-general] Regd routing daemons and OSPF

[kavitha g. <kav...@ho...>]

Hi Ramon,

I did take a look at the OSPF TE RFCs and other related RFCs. I have also 
gone through the code for OSPFAPI  and could get the LSA header information 
through the ospfapiclient. But the problem is the ospf daemons on each of 
the routers are communicating but not the routers themselves. That is I give 
a telnet or ping from one to another, there is no response. Basically, I 
have mpls enabled linux kernel rpm installed, source code for zebra with the 
ospfapi. I have tried with ldp and rsvp as signaling protocols. But in vain. 
When I installed the zebra-ldp rpm and ran the opsfd it pings fine. When the 
ospfd from the source (zebra with ospfapiclient) is running why doesn't it 
ping.

Please let me know,
I am all stuck,
Thanks a lot,
Kavitha
