[j-nsp] ECMP in Virtual Router and IP-Track

[Blake Willis]

Greetings Mytel,

Regarding your "IP tracking" question, the feature is called "IP Monitoring with 
Route Fail-over":

AFAICT it's only supported on branch SRX at the moment, but you could certainly 
try it on your bigger boxes with a recent 12.1X build.  If it's not there then 
you really should bug your account team about it as this is one of the "but 
Crisco does it!" features missing from JunOS for a long time (along with CLI 
aliases that don't eat CPU by executing a script...).

Of course they also "suggest" using this scripted mess if your platform doesn't 
support the new feature:  http://www.juniper.net/us/en/community/junos/script-automation/library/event/track-ip/ 
Probably works fine for a few routes but I wouldn't want to make a habit of 
using that or roll it out at scale...

Best of luck,
