Route Server Module (20N41)
The Route Server module supports internet protocol (IP) virtual private net-
works (VPNs). Each VPN supports routing information protocol (RIP version
1 and version 2) and can be assigned to multiple IP interfaces and static
routes. The module can interact with any other Multiservice Media Gateway
module port that is configured for frame relay, bridge, or asynchronous
transfer mode (ATM). All traffic on the Route Server module runs through IP
in compliance with media access control (MAC) encapsulation:
•
IP over ATM (RFC 2684)
•
IP over frame relay (RFC 2427)
•
IP over Ethernet
Note:
RFC 2684 supercedes RFC 1483. The Route Server module supports
RFC 1483 and RFC 2684, but RFC 2685 (VPN identification) is not
supported. RFC 2427 supersedes RFC 1490.
These interfaces can be mixed (that is, IP over ATM to IP over frame relay),
but may be routed same service type to same service type. Further, the traffic
can come from any I/O module supporting this traffic type.
The Route Server module can be configured through either the Multiservice
Media Gateway system console or through the simple network management
protocol (SNMP). Each Multiservice Media Gateway system may support
multiple Route Server modules, but multiple Route Server modules cannot
be configured for hot-standby redundancy purposes.
Software Release 6.3.0 introduces routing information protocol (RIP) Version
2 to the Route Server module. The module now supports Internet Protocol
virtual private networks (VPNs) by assigning multiple IP network interfaces
and static routes. (The Route Server module also supports RIP v1.0, and can
interact with any other PSAX module port that is configured for frame relay,
Ethernet bridging, or ATM.)
