DES-7200 Configuration Guide Chapter 6 BGP
Configuration
6-34
Command Function
DES-7200(config-router)# neighbor
R2 remote-as 100
Configure R2 as the BGP neighbor
with the AS number of 100.
DES-7200(config-router)# neighbor
R1 remote-as 100
Configure R1 as the BGP neighbor
with the AS number of 100.
Step 2: Since R3 does not need to transmit multicst route with R1, disable the
multicast address of R1.
Command Function
DES-7200(config-router)#
address-family ipv4 multicast
Enter the IPv4 multicast address
family configuration mode.
DES-7200(config-router)# no neighbor
R1 active
Disable the multicast address of R1.
Step 3: Since R2 needs to transmit multicast rotue with R1, enable the multicast
address of R2.
Command Function
DES-7200(config-router)#
address-family ipv4 multicast
Enter the IPv4 multicast address
family configuration mode.
DES-7200(config-router)# neighbor R2
active
Enable the multicast address of R2.
Step 4: Import the routes that R3 needs to advertise to R2 in the multicast
address family mode.
Command Function
DES-7200(config-router)#
address-family ipv4 multicast
Enter the IPv4 multicast address
family configuration mode.
DES-7200(config-router-af)#
redistribute ospf 1
Redistribute OSPF routes.
Caution
During redistribution, the routes imported are unicast routes. For instance, the
redistribute ospf 1 command imports OSPF unicast routes. This is because
that multicast routes actually depend on the egress of unicast routes for the
establishment of multicast spanning tree.
6.22 Configuring BGP Local AS
This function configures a local AS different from the real AS (rotuer BGP AS) for
