We used to use "ip tcp adjust-mss" a lot for applications where PPPOE was required..... ie Cisco 877 router at customer premise connecting via PPPOE back to us.
Never seen it in MPLS core functions though if that's where it's being used..

Very common hack to deal when tunneling is involved in middle of the network, and reducing client MTU is not practical. But I'm really surprised you'd need it in this situation, usually you can increase your core MTU to carry MPLS labels while still delivering customers 1500B. Mostly while quite ugly hack, it just works. Sometimes you run into some poor application which send MTU size UDP frames and expect them to be delivered, those customers would not be happy. -- ++ytti _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
