RE: Multiple ABR for a particular Area? [7:60654]
BTW, it works perfectly well with HSRP also: 2 routers connecting an area to area 0.

Re: Multiple ABR for a particular Area? [7:60654]
I certainly hope so. If you're only allowed one ABR per area, then when that ABR fails, that area is totally cut off. It would mean that every ABR in your network would be a single point of failure, and would basically mean that nobody would ever use OSPF.

In fact, you could have (trust me that there's a link between the parts of area 3 serviced by R1 and R4 --it would be too painful to draw this in ASCII R1R2 R3R4 area 3 + area 1 area 1 + area 2area 2 + area 3 area 3 + area 1 Cisco's conservative rule is not more than 3 areas per ABR, although I've never found a reference that made it clear whether they are counting area 0.0.0.0 in that. I've certainly had carefully chosen situations where I had an ABR servicing seven nonzero areas, with extensive summarization and very stable physical plants.
