I have a client complaining of slow WAN links. He
has 3 hub routers, each with about 5-7 remote links.
They are all running OSPF. The remote sites are not
configured as stub areas even though there is nothing
behind them (I will remedy that).
What I noticed was that the remote router Serial
interfaces all had high 'out bcast bytes', that
averaged out to 1.5 MB a day. Some of those routers
have only been up 5 days and some of them have been up
15 weeks, but somehow they have all managed to average
1.5 MB a day. And the only thing I can think of that
would show up as broadcasts on the Serial interface is
OSPF and CDP.
They only have 2 subnets listed under OSPF with a
total of 50 routes when I do a show ip route. The show
ip ospf database is relatively small too - I only need
to hit spacebar once to see entire database.
Anyone have any ideas if 1.5 MB is high? I think it
is since there are not alot of routes and there
shouldn't be any changes since it's a stub router. The
30 minute updates and CDP shouldn't contribute much
either.
Thanks.
