Inter-VLAN Communication

Its definately a strange one. One of them gremelins i think, if it does re-occur i suppose we could try a reboot of the switch to see if anything in the cache is causing issues (or i suppose we could just clear the cache's)

Please let us know if it re-occurs as its got me interested also.

Have a good Christmas

Hi,

I got the same problem again :oops: today but after sometime it get resoved automatically...one of my Colleauge adviced that there is routing issue thats the way its happening like this...OSPF is the routing protocol

Can some one tell me how to confirm the routing issue?

Any suggestions on this please...!!!

Sorry Dove but i have not done much with routing protocols yet (thats one of my next CCNP Exams).

I would probably first start with some traceroutes first to see exactly where along the path its failing. Once you have done that you can hop onto the switch to check out the routes that it has (this will also list the OSPF routes).

I am not 100% sure that this issue is a routing issue, from the original post it says that both server A and B are on the same switch, if thats the case then it shouldn't be relying on any routing protocols because they subnets are physically connected to the switch (on the different VLAN's).

When it occurs, if you try some basic troublshooting to see where the packets are going and also ensure that the VLAN's are up and test pinging each server from the switch itself.

Please let me know how you get on because i am curious myself now.

Cheers
