Re: OSPF - MTU mismatch posted 11/15/2003

I've checked the 3550 documentation and didn't see anything regarding the
need to change MTU for OSPF or any other routing protocol for adjacencies to
properly form.  Is this problem specific MTU size documented anywhere or is
this something that you had best just know.

Thanks
