link protection of 5.4
Hi, All,
In JUNOS5.4, TE link protection feature,I found if we protect a give LSP
whose path is manually strict defined, even configuring link-protection
in LSP and RSVP, the link protection and head-end re-calculation can't
work.
We found when it's ok, the protection LSP is ok(2 LSP setup). During the
protection situation, because there's no way to the manually defined
strict path, the headend can't setup a new LSP replacing the old one.
At the same time, link-protection LSP is down, can't carry the traffic
before the new LSP re-calculated.
What's wrong?
Thanks,
Liu Jun
