route table size

[Netwow]

I need to know what is the maximum number of routes in an MX 64 and MX 450 route table.

I don't know the answer.

From the MX sizing guide, you can assume the minimum number of routes is equal to the number of concurrent AutoVPN tunnels supported (which generates a minimum of 1 per tunnel).

For an MX64 that is 50.

For an MX450 that is 1,000.

The answer is very useful, but is that it?

what happens when you follow standard practice and split out routes for IP phones voice subsets from data service - does that cut the number of supported site by 50%?

The routing table needs to handle more than just Auto VPN

- IPSec tunnels are going to need a WAN subnet as well as a target for far end LAN

- static routes or

- dynamic routes pointing for BGP / OSPF

or do any internal routes really reduce the number of tunnels available?
