I am marking packets with dscp on the edge of the network but after the packets have been through the mpls core (6500's with sup720's) only the equivalent ToS value is in the header.Anyone know of a way to preserve the full DSCP value?
I have 4 6506 with SUP720-3BXL connected via 100Mb ethernet links as below. (you may have to copy the diagram to look at it using a fixed font) r3---utp---r4 |.........| media......| converter..| |.........| fibre....Telstra 2Mb Ethernet ser...
CET generates new session keys every 30 minutes (by default). In some instances I am seeing this take several retries and several minutes to successfuly happen. The end result is lost sessions during this time. Is there a way to prevent this?
Hi,I have a similar requirement where we are using GRE/IPSec tunnels between the PE and CE. I have tested this in the lab and found the following results. With multiple GRE only tunnels between PE and CE it works with all tested IOS versions.With mul...
Francesco,I have a 6500 with Sup720-3B in the lab for a few days. I have been able to confirm your results. I also tried using a policy map to set the mpls exp bits, but this appears to not work either.In trying to validate my results I found that th...
Francesco,I am running 12.2(17d)SXB1 so I don't know about that later version. I haven't had a chance to test the policy-route work around as I don't have a spare 6500 with Sup720 to try it on.Michael
Thanks for that reference it is a very useful document, however I think I may be restricted by this bug.'With a PFC2 or a PFC3, you can either set DSCP in a packet or apply an MPLS tag to the packet, but cannot do both. You cannot set DSCP in a packe...
