DES-7200 Configuration Guide Chapter 6 BGP
Configuration
6-6
The table-map command supports the following rules-match,
as-path/community/ip address/ip next-hop/metric/origin/route-type, set,
metric/tag/next-hop.
Control the route redistribution from IBGP to IGP
The BGP protocol controls the redistribution of the routes learnded from the IBGP
protocol to IGP protocol by the bgp redistribute-internal command. The routes
learned from the EBGP protocol or confederation are allowed to be redistriubted
to the IGP protocol.
To redistribute the route to the IGP protocol (inclding RIP/OSPF/ISIS), execute
the followin command in the BGP configuraiton mode, IPv4/IPv6 address family
configuration mode or IPv4 VRF address family configuraiton mode:
Command Function
Router(config-router)#
bgp-redistirbute-internal
Redistribute IBGP routes to the IGP
protocol.
Use the no bgp redistribute-internal command to remove the configuration.
6.6 Configuring BGP Peer (Group) and Its Parameters
Since the BGP is an external gateway protocol (EGP), it is necessary for a BGP
Speaker to know who is its peer (BGP Peer).
It is mentioned in the overview of the BGP protocol that two modes can be used
to set up the connection relationship among BGP Speakers: IBGP (Internal BGP)
and EBGP (External BGP). It will judge which connection mode will be
established among BGP Speakers by the AS of BGP Peer and that of the BGP
Speakers.
The BGP protocol supports IPv4 and IPv6. To check IPv6 function, verify whether
the address-family ipv6 command is executed in the BGP configuration mode.
Otherwise, IPv6 is not supported. Note that you should activate neighbors in the
corresponding address family.
In general, the BGP Speakers with EBGP connection should be physically
connected. The BGP Speakers with IBGP connection, however, can be located in
any place within an AS.
To configure the BGP peer, execute the following operations in the BGP
configuration mode:
Command Function
DES-7200(config-router)# neighbor
{address|peer-group-name}
Configure the BGP peer.
address indicates the IP addresses of
