Associating a Profile with an Interface for RIPng
The profile statement associates a profile on a particular interface. If the profile id is not specified, a
default profile (id 0) is used.
The syntax of the profile configuration statement is as follows:
profile id;
where id specifies the profile ID on a particular interface.
Route Filtering Based on Interface for RIPng
You can specilfy the list of route filters for a specific interface. If no filter is configured, filter policies are
not applied to the RIPng packets that are sent and received on this interface.
The syntax of the filter configuration statement is as follows:
filter dir (in|out) route-filter-name-list [
allow
|restrict];
where the following means:
in|out Specifies the direction to apply the filter.
route-filter-name-list
Specifies a space separated list of multiple route filters to associate with this filter.
allow|restrict;
Let ripngd allow or restrict route information that matches the route defined in the route
filter. If the allow or restrict option is not specified, the default option is
res-
trict
.
Note: This configuration statement accepts only one filter statement per interface.
BGP SECTION OF THE CONFIGURATION FILE
The following describes the BGP section of the RAMD configuration file.
BGP Protocal Overview
BGP protocol runs over TCP. The key features of the BGP protocol are as follows:
• The BGP routing protocol uses the standard port number 179.
• The BGP routers exchange routing information with its peers. A peer in a different Autonomous System
(AS) is in an external peer and peer in the same AS is internal peer.
• The BGP routers use the path vector algorithm to select the best route for installation.
• The BGP protocol runs as a daemon process. The BGP daemon can be configured through the BGP pro-
tocol section of the RAMD configuration file, /etc/ramd.conf
.
• The BGP routers send the best route to
ramd for updating the IPv6 kernel routing table.
• The BGP router enforces policy decisions on routes installed and advertised.
Enabling BGP
The RAMD configuration file is used to enable or disable the BGP protocol. If the BGP section is not
specified in the configuration file, by default, bgpd is off.
The syntax for enabling BGP is:
bgp (on|off) {admin (up|down); [snmp (on|off);] };
where the following means:
bgp (on|off)
Enables or disables BGP protocol. By default, BGP protocol is disabled.
admin Specifies the administrative status of the BGP protocol. By default, administrative status is
up.
snmp Enables or disables SNMP support in bgpd. When on is specified, bgpd subagent registers
with the snmpdm(1M) master agent and accesses the SNMP operations like GET, SET, and
GET-NEXT. bgpd supports enterprise-specific MIB based on SNMPv2C. bgpd implements
EMANATE subagent. By default, snmp is off.
Please note that as and routerid are mandatory parameters when BGP is on.
