Hello,

I need that information if it is available:

How many OSPF peer does Cisco router support? For example; Cisco 7206VXR

router supports how many OSPF peer on its one of the ethernet or serial

interface?

It's depending on allot of verities for example the OSPF router may have multiple point-to-point interfaces into different areas or the same area (As per Cisco recommendation the router should not belong to more than 3 different areas) I the same time the router may be elected as the DR on the Ethernet segment so finally it?s deepening on the router resources.

Welcome Mounir... good to see you back in the forum

Yes i agree with Mounir that it totally depeneds on the router resources.

These are however some Cisco OSPF design recommendations

routers per area - 50

neighbors per router - 3

areas per router - 3

Bit again this may differ according to your network topology and traffic patterns

You could also consider forcing your down stream routers to only create two adjacencies with the DR and BDR to speed up convergence.
