Guys, I apologize if this is a lame-brain question but I am new to MPLS... We have a pretty simple MPLS VPN setup comprised of the following 3 routers:
PE1 <------> P <-----> PE2 PE2 is a new router we are transitioning customers to. PE1 is 7206VXR 12.4(17) PE2 is CAT6513/SUP720-3B 12.2(18)SXF12 the P router is a Cat5500 catos6.4(23a) / RSM ios12.2(46a) the P to PE2 link is a 1GB link on a WS-X5410 blade. According to cisco's Catalyst Jumbo Frame documentation this blade does not support a larger mtu than 1500. However if you enable dot1q trunking yet transmit on the native VLAN the switch will accept an additional 4 bytes. My question is, since the P router will always be the penultimate hop in this layout ? will having room for just 1 label be sufficient? Also the RSM in the cat5500 only supports TDP for label distribution ? Any potential drawbacks to this?
