rekey on sequence
number overflow
An IPsec option that automatically reestablishes the SA before it reaches the
last sequence number.
remote access Communication with a network from a remote location.
remote gateway The VPN gateway of the device that is at the other end of the VPN tunnel.
remote mirroring Technology that enables you to send mirrored traffic from network devices to
a remote analyzer using the network infrastructure rather than a dedicated
line.

RIP Routing Information Protocol. A protocol that allows routers to tell other
routers which routers they can reach and how far away those routers are. For
more information, see RFC 1058 for version 1 at http://www.ietf.org/rfc/
rfc1058.txt or RFC 2453 for version 2 at http://www.ietf.org/rfc/rfc2453.txt.
route computation The process of adding route costs in OSPF to find the shortest route to an
arbitrary destination.
route
redistribution
The process of using routes discovered by a different protocol. For example,
RIP can redistribute routes discovered by OSPF, so RIP learns about routes that
it may not otherwise have been able to reach.
router ID An identifier in IPv4 address format for an OSPF router.
routing mode The default, Layer 3 operating mode of the module where the VLANs are
associated with zones, and firewall, NAT, routing, and
VPN capabilities are
available.
RP Rendezvous Point. The point to which IGMP group members send multicast
traffic. Each IGMP group has one RP.
