Configuring Ip Rip For A Remote Site - 3Com OfficeConnect Remote 812 Cli User's Manual

Configuring IP RIP for a
Remote Site
The IP address associated with the local side of the WAN connection can be
specified by you, learned from the remote site (if you are using PPP as the Network
Service for the connection), or the interface can be Unnumbered.
To specify the local IP address use the command:


set vc <vc name>
local_ip_address <ip address>
To specify that the local IP address should be learned you must enter
255.255.255.255 for the <ip address> parameter. To specify that the interface is
Unnumbered you must enter 0.0.0.0 for the <ip address> parameter.
For a discussion of Unnumbered (and Numbered) interfaces, see "Configuring IP
Routing" in the Online User's Guide.
Optionally, you can specify that the remote site should be used as the default
gateway.
To designate the remote site as the default gateway use the command:


set vc <vc name>
default_route_option [DISABLE | ENABLE]
The default_route_option can only be enabled in one VC profile.
Also, you can configure IP Source Validation for the connection. When IP Source
Validation is enabled, the source address of all IP frames received from the remote
site will be validated. A packet's source address is valid if the OCR 812 will route an
IP frame destined to the source address on the same VC it came in on.
To enable IP Source Validation in a profile, use the command:


set vc <vc name>
ip_source_validation [DISABLE | ENABLE]
To create a filter to block NetBIOS file and printer sharing over the Remote Site


connection, use the following command:
add auto_filter vc_blk_netbios vc <user name>
Where <user name> is the VC Remote Site profile name.
This command creates a filter which rejects incoming frames with destination UDP
ports 137 and 138, and destination TCP ports 139 and 143. The filter is
automatically added to the filter manager and attached as the Remote Site's
profile input filter.
IP RIP can be enabled or disabled for each remote site connection.
The OCR 812 supports two versions of RIP, V1 or V2. Additionally, you can
configure whether the OCR 812 should advertise local routes, only listen for routes
from the remote site, or both.
To configure RIP for a remote site connection:


set vc <vc name>
ip_routing [BOTH | LISTEN | NONE | SEND]
IP Routing 6-17
