I run the backbone/area 0 only. But I have less than 15 routers speaking OSPF. Convergence time is fine so I see no reason to go to multi-area any time soon. On 9/8/2015 12:39 PM, Christopher Gray wrote: Can an area have multiple ABR routers connecting to area 0 (Is there any way to add

Re: [AFMUG] Some OSPF Questions...

I have everything in area 0 too, and we've get well over 100 routers running OSPF and I really don't see any good reason to change it at this point. On Tue, Sep 8, 2015 at 2:08 PM, George Skorup wrote: > I run the backbone/area 0 only. But I have less than 15 routers speaking

Re: [AFMUG] Some OSPF Questions...

The blog article seems to imply an area can have multiple ABRs. It looks like I'm quite far from needing areas, but I'm also entertaining them as a mechanism to separate customer IPs from the backbone area. I'll continue with a single area for the time being. I am still interested to know whether

[AFMUG] Some OSPF Questions...
