<BR>
As far as I know, this inter context routing is supported with IS-IS.<BR>
The interface between the contexts can be defined as p2p or as broadcast segment, so /24 instead of /30, where each context would get it’s own IP address.<BR>
I would try to go with the broadcast option and define OSPF in broadcast mode, however, this is pure theoretical.<BR>
<BR>
So far I have seen working implementations based on IS-IS between the contexts.<BR>
<BR>
Kind regards,<BR>

<BR>
</SPAN></FONT><SPAN STYLE='font-size:11pt'><FONT FACE="Arial">Hi all,<BR>
<BR>
I'm trying to configure some intercontext routing with OSPF having the following config:<BR>
<BR>
########################################<BR>
context local<BR>
<BR>
interface bla intercontext p2p 1<BR>
ip address 10.0.0.1/30<BR>
<BR>
router ospf 6714<BR>
fast-convergence<BR>
router-id 10.0.0.1<BR>
area 0.0.0.0<BR>
interface bla<BR>
neighbor 10.0.0.2<BR>
redistribute static<BR>
<BR>
ip route 10.0.0.2/32 context test<BR>
<BR>
<BR>
context test<BR>
<BR>
interface bla intercontext p2p 1<BR>
ip address 10.0.0.2/30<BR>
!<BR>
router ospf 6714<BR>
fast-convergence<BR>
area 0.0.0.0<BR>
interface bla<BR>
neighbor 10.0.0.1<BR>
redistribute static<BR>
!<BR>
ip route 10.0.0.1/32 context local<BR>
########################################<BR>
<BR>
I can ping each other interface bla from each context. In context test is only this one ip address existing. So I think there's no need to configure router-id there.<BR>
But the two OSPF processes don't exchange updates. <BR>
<BR>
Am I missing something?<BR>
<BR>
<BR>

Kind regards<BR>
