11.4 Routing Functions

The Multiprotocol Interconnect module supports the following routing protocols:

11.4.1 IP Routing Support

When acting as an IP router, the Multiprotocol Interconnect module provides
support for:
11.4.1.1 RIP Implementation
The following is a summary of the RIP implementation in the Multiprotocol
Interconnect module:
11.4.1.2 OSPF Implementation
The following is a summary of the OSPF implementation in the Multiprotocol
Interconnect module:
IP
IPX
DECnet Phase IV
Directed broadcast
ICMP
Proxy ARP
Ethernet or 802.3 (not both) encapsulation on LAN interface
Datagram fragmentation/reassembly support
IP security
Boothelper
Static routes
Dynamic routes
RIP
OSPF
Routing messages are broadcast every 30 seconds.
Triggered updates are sent.
Split horizon with poison reverse is always used.
Host level routing is supported (with future WAN I/O cards).
RIP can be enabled/disabled on a per logical port basis.
RIP can be enabled/disabled globally.
Path cost can be configured on each logical port.
Routing table entries are aged-out to ensure validity of routes.
Can pass or block datagrams according to user defined security access list.
Only topology changes are broadcast as per OSPF Specification Version 2
(RFC 1247).
Supports alternate routes based on IP Type Of Service (TOS).
Supports multiple paths with equal costs.
