Thanks Nick.  I admit that since transitioning roles, I hadn't been
keeping track of XE.  I'll need to now go find a platform to play with
it on.

Do you know if it supports things like ECMP with filtering?  The config
guide doesn't seem to indicate.  Also it will be interesting to see how
it will handle the BGPSEC cases.
