TE in MPLS question

[teru-lei]

Hi All,

To enable TE in MPLS, should I need to enable RSVP in every hop or just the head end and tail end? (I think it should be every hop) And when I see the TE information, it said that TE just support in 7500 series routers or above, did it mention just the head end and tail end routers or routers in every hop?Thank You!

Best Regards

You need to enable RSVP on any interface you might potentially use to create the TE Tunnel.

BTW: MPLS TE is also supported on smaller platform.

Thank you! I tried to do TE in 3600 routers and it works!
