Maximum number of neighbors/adjacencies (per area): 128
Maximum number of routes (per router): Unlimited
Maximum number of OSPFv2- ECMP gateways (per destination): 4
Max number of OSPFv2 Sessions: 1
The following values are the tested limits with the functionally verified (stress test).
On OS9000 ABR routers:
Tested number of IP Routers on OS9000 router: 32K
Tested number of OSPFv2 Routes on OS9000 router: 32K

On OS9000/OS6850 non-ABR routers:
Tested number of IP Routers on OS9000/OS6850 router: 96K
Tested number of OSPFv2 Routes on OS9000/OS6850 router: 96K
Tested number of OSPFv2 Interfaces on OS9000/OS6850 ABR: 27
Tested number of OSPFv2 Areas on OS9000/OS6850 ABR: 6
Tested number of OSPFv2 Adjacencies on OS9000/OS6850 ABR: 27
Tested number of LSAs on OS9000/OS6850 ABR: 24K
Tested number of OSPFv2- ECMP gateways (per destination): 4
Tested number of OSPFv2 Sessions: 1
ECMP Only 512 networks can be programmed in the ECMP table, so that the flows can be load balanced
among the different paths.
When having more than 512 ECMP routes on the “show ip route”, only the last (highest) 512 routes
are programmed in the ECMP table.
• Only 512 networks can be load balanced over ECMP links
• The other “ECMP networks” will always be routed on the same link (single path used).
