VRRP Groups EX4300

‎05-19-2016 01:17 AM

Dear All

 

I had an issue about a month ago with a EX4300 Virtual Chassis which Juniper Support helped resolve (2 thumbs up to Juniper Support to get the issue fixed).  During the support call the Engineer asked for a copy of the configuration (RSI).  When they examined the configuration they noticed we had 14 IP address in one VRRP group and the maximum number should be 8 IP Address per VRRP Group.  This was not the cause of the issue, but Juniper have advised I should split the IP Address down to more groups.

 

I have VRRP setup in a couple of different location and most of these location are not on the same layer2 network.

My Question is, if I have 2 different VRRP-groups setup, one at site A and one at site B and I use the same VRRP Group ID and I connected the 2 sites at layer2 with no security between the 2 sites will VRRP try and converge the VRRP groups at site A and site B into one large VRRP group?  Is there a way to say which Virtual Chassis's are a part of the VRRP Group.

 

And what is the maximum number of VRRP-group's I can have, or should I say what is the upper limit of the VRRP-Group ID?

Hi Richard.Moth@ebiqui…,

 

 

"will VRRP try and converge the VRRP groups at site A and site B into one large VRRP group?"

 

Yes.

 

" Is there a way to say which Virtual Chassis's are a part of the VRRP Group."

 

Not a direct method, unless you create a script that polls your switches in every vrrp group for its chassis cluster.

 

"And what is the maximum number of VRRP-group's I can have, or should I say what is the upper limit of the VRRP-Group ID?  "

 

256 groups ( from 0 to 255 )

Thanks,
