don't use ISIS :-)<br>

if you do it all in one go and get it right first commit , you may not get much of an outage (I assume its a live interface is why you're wary of deleting) but you're bound to drop something.<br></blockquote><div>
<br>We had very bad experiences deleting/adding interfaces on a single commit transaction, so much, that we now do it in two commits as standard practice. The interfaces I have to change are around 50-60, with LDP, BFD, OSPF which is why I cannot understand how IS-IS p2p was implemented this way.<br>

I'd do it in a network maintenance window.<br></blockquote><div><br>It will be a looong and painful one, I hope Ericsson comes out with another solution for future releases<br><br>Thanks,<br>Mariano<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Hi everyone,<br>
<br>
I'm trying to configure all my IS-IS interfaces as p2p links in order to<br>
avoid an ugly bug with non-p2p ISIS links on our target upgrade release<br>
(6.1.3.7)<br>
<br>
There seems to be no command like "network point-to-point" and the<br>
documentation shows this example for p2p;<br>
<br>
[local]Redback(config)#context local<br>
[local]Redback(config-ctx)#interface lo0 loopback<br>
[local]Redback(config-if)#ip address <a href="http://10.1.1.1/32" target="_blank">10.1.1.1/32</a><br>
<br>
[local]Redback(config-ctx)#interface to-core2 p2p<br>
[local]Redback(config-if)#ip unnumbered lo0<br>
<br>
[local]Redback(config-ctx)#router isis my-backbone<br>
[local]Redback(config-isis)#net 47.0001.1111.2222.3333.00<br>
[local]Redback(config-isis)#interface to-core2<br>
<br>
The config implies that the ip interface itself needs to be declared as p2p,<br>
which means that if the interface already exits it has to be removed first.<br>
<br>
I'm hoping there is another to declare IS-IS interfaces as p2p without<br>
having to erase them.<br>
<br>
How do others here manage this situation?<br>
<br>
Regards,<br>
<br>
Mariano<br>
