Before You Configure Redundancy for a Redirect Server

If you plan to use a redundant configuration for the redirect server, ensure that:

If you use a next-hop address for policies that capture Web traffic and send it to the redirect server, that the virtual IP address to be used is also the next-hop address.
The redirect server has SNMP write access to the virtual routers connected to it. Each VR must have at least a write community configured. (The static route from the virtual IP address to the server’s real IP address is installed on the router through SNMP.)
If additional access controls are enabled on the JunosE router, the hosts on which the redirect server runs must be included.
