I am running into a wall, the ASR sends T Spec mtu of 500 for an RSVP LSP. However, 500 is not set anywhere. I have the following MTU set: (Including snip bits from configuration, see below) Essentially the setup is an RSVP-TE LSP and a L2PW utilizing the LSP. The remote end is sending 9198, however since the ASR is sending 500, 500 the lower mtu is negotiated and used. <[email protected]>HundredGigE0/1/0/0 is Up, ipv4 protocol is Up Vrf is default (vrfid 0x60000000) Internet address is 13.1.1.1/24 MTU is 9212 (9198 is available to IP) RP/0/RP0/CPU0:ios#show running-config interface Tue Jul 30 18:02:22.481 UTC interface Loopback1 ipv4 address 1.1.1.1 255.255.255.255 ! interface tunnel-te1 ipv4 unnumbered Loopback1 mpls mtu 9198 ! destination 7.7.7.7 path-option 1 dynamic ! interface HundredGigE0/1/0/0 mtu 9212 ipv4 address 13.1.1.1 255.255.255.0 mpls mtu 9198 ! interface HundredGigE0/1/0/1.1 l2transport encapsulation dot1q 1 second-dot1q 1 mtu 1528 !
