<div>I’ve got some MLXe’s talking to ASR’s with ospf/ospfv3. I do seem to have a hard coded MTU in there but can’t remember why. On the brocade side, ve interface:</div>
<div><br>
</div>
<div>
<div> ip mtu 1500</div>
<div> ip ospf area 0</div>
<div> ip ospf md5-authentication key-id 111 key 1 yyyyyyy</div>
</div>
<div> ipv6 mtu 1500</div>
<div>
<div> ipv6 ospf area 0</div>
</div>
<div>
<div> ipv6 ospf authentication ipsec spi 222 esp sha1 encryptb64 xxxxxxx</div>
</div>
<div><br>
</div>
<div><br>
</div>
<div>And on the cisco side vlan interface:</div>
<div><br>
</div>
<div>
<div> ip ospf authentication message-digest</div>
<div> ip ospf message-digest-key 111 md5 7 yyyyyyy</div>
<div> ip ospf 65535 area 0</div>
</div>
<div>
<div> ipv6 ospf authentication null</div>

</div>

<div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">
I’m having trouble getting OSPFv3 up between a Brocade ICX7750 and a Cisco 4500X. I’ve found on cisco-nsp where someone else found a working config using the following:
<div class="">
<pre class="">Brocade side:
ipv6 ospf authentication ipsec spi #### esp sha1 KEY
Cisco side:
ipv6 ospf authentication null
ipv6 ospf encryption ipsec spi #### esp null sha1 KEY</pre>
<div class="">Well, I’m already doing OSPFv3 between Brocades using the exact line in the example, which is good. I also have OSPFv3 neighbors up with our firewall (not Cisco). However, when I use the Cisco side of the example I don’t get a successful neighbor.
On the Brocade side, I see a neighbor in the neighbor table, but it’s stuck in INIT state. On the Cisco side, the neighbor table is empty.</div>
<div class=""><br class="">
</div>
<div class="">Normally when it’s stuck in INIT state, I’d check MTU sizes and general connectivity between both sides. Both are 1500 bytes and both sides can ping each other.</div>
<div class=""><br class="">
</div>
<div class="">Does any one have any ideas as to what I can look at next, or if they have a working config that’s different from mine? I can’t remove the authentication without having to clear that out of my network everywhere. </div>
