Hi
ali.taheri,
I think you mean LSInfinity which is:
16-bit (
65535 ) for Router LSA
24-bit (
16777215 ) for Summary LSA and External LSA
We can find from
RFC3137:
To address both problems, router X announces its router-LSA to the
neighbors as follows.
o costs of all non-stub links (links of the types other than 3)
are set to LSInfinity (16-bit value 0xFFFF, rather than 24-bit
value 0xFFFFFF used in summary and AS-external LSAs).
o costs of stub links (type 3) are set to the interface output
cost.

Subject: Highest accumulative OSPF Metric allowed
Hi guys! it suddenly became a question today when I was troubleshooting an ospf network where metrics are done manually! what is the maximum metric allowed on ospf, something equivalent to RIP 16hop limitation but in terms of ospf. here is a simple topology:
R1 <--link1--> R2 <--link2-->R3 <--link3--> R4 where we run OSPF on links 1-2-3 with a metric of 65000 on all routers for testing purposes.
R1 also has its loopback part of Ospf, 1.1.1.1/32.
R2 sees lo0 /32 with metric of 65k, R3 sees it with metric of 130k and R4 sees it at 195k! is there a maximum value that ospf honors? whats the highest number allowed?
Thanks everyone!
