I’m designing an OSPF network for a client’s new VPLS cloud. I’ve done this before using a /24 for the interface uplink to the VPLS. I’m curious if anyone has experience with larger (or even this large) of a subnet for OSPF broadcasts.
The client already has around 100 routers running OSPF, all in area 0. Not the best design, I know - but until we can redesign their entire network we’re stuck with it. The VPLS deployment will be for edge devices and I’d like to know if anyone has had successful deployments with 100+ routers in a single broadcast and OSPF area.
Routers are ISR 4331 and ASR 1004s (for the DR and BDR).
Thanks in advance!
