[j-nsp] 1000 VRRP instances per IFD and IRB

[Ross Vandegrift]

Hey guys,

Accoridng to our account team, VRRP scales to about 1000 instances per
IFD.  Not that I want to scale beyond Juniper's tested specs, but has
anyone pushed on this?

Anyone have any experience on many VRRP instances per IFD?  How many?
We're planning on doing vrrp inheritance so only a single IFL is
actually sending keepalives to keep that work to a minimum.

Is there any way to get more IRB IFDs?  Per-interface limits aren't a
major problem for ethernet interfaces - this is a datacenter, we run a
few more cables.  But it's crippling for virtual interfaces.  We'd
love to toss 4000 or so customer VLANs into individual VPLS with IRB,
but we can't justify the cost of 4 pairs of MXes to get more IFDs for
VRRP instances.

Ross
