http://www.cisco.com/en/US/products/ps6566/products_feature_guide09186a0080629db0.html "This document explains the the behavior of the mpls mtu command in Cisco IOS Release 12.2(27)SBC, 12.2(33)SRA, 12.4(11)T, 12.2(33)SXH, and later releases. You cannot set the MPLS MTU value larger than the interface MTU value. This eliminates problems, such as dropped packets, data corruption, and high CPU rates from occurring when MPLS MTU value settings are larger than interface MTU values." -- "Don't expect me to cry for all the | Łukasz Bromirski reasons you had to die" -- Kurt Cobain | http://lukasz.bromirski.net _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
