Bird/Cisco OSPF interaction

Found an interestnig issue running bird in Talisman code on a WRT54G 
router. I could not develop a neighbor relationship with my Catalyst 
3560 running 12.2(25)SEC2 and then 12.2(25)SED advanced ip services code.

An Ethereal trace revealed that the 3560 was sending EA options, while 
the WRT54G was sending E options. A further search revealed that 
Ethereal decode is incorrect and that the option is Local Link. A change 
to the config on the 3560 OSPF process (no capability local-link) 
resolved the issue.

Just thought I'd post in case anyone else experiecnes the issue.
