Hi Kireeti,

Keep it out of scoop.

Thanks,

Subject: [mpls] RMR updates

Hi All,

We'd like to move to last call on the RMR document, but first there are a couple of loose ends we'd like to tie up, specifically, the "Advanced topics" in the -05 version of the draft.

a) how should the RMR document deal with "half-rings"?

Consider the following half-ring:

    A    B

    |    |

    C----D

Here are some options:

i) the RMR document shouldn't concern itself with this case

ii) create a PW from A to B to complete the ring

ii) instead of creating N LSPs (in this case 4), only create LSPs from A to B and from B to A.

b) how should the RMR document deal with protecting hub nodes?

i) not deal with it.

ii) use technology akin to PIC edge

We feel that it is important to address both these issues. We are soliciting your response, either among the options suggested, or potentially other ideas.

Thanks,
