[j-nsp] Router with lots of layer 3 interfaces

[Andrew Jones]

Hi,
I have a requirement to terminate the layer 3 for about 2000 vlans on a
pair of routers of some kind, with failover in the event of one of the
routers dying. Is this something that SRX240Hs could do? How many layer3
interfaces can the SRX240 handle? SRX650? Throughput is not a huge concern,
each vlan only requires a small amount of bandwidth.

To handle the failover, I could use the clustering, although that would
mean any software upgrades would require a simultaneous reboot of both
devices, making it a less desirable solution than having two SRXs with VRRP
on each vlan-facing layer 3 interface which would allow me to reboot the
boxes one at a time. My question with that setup is: how many VRRP
instances can I have on an SRX?
I appreciate any advice/feedback.
Thanks,
Andrew
