Example:
RP/0/RP0/CPU0:router(config-bgp)# neighbor 172.16.0.1
Enters the neighbor configuration mode for configuring BGP routing sessions.
Step 7
ebgp-recv-extcommunity-dmz
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# ebgp-recv-extcommunity-dmz
Receives the DMZ link bandwidth extended community to the eBGP neighbor.
Step 8
exit ip-address
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# exit
Exits the neighbor configuration mode and enters into BGP configuration mode.
DMZ Link Bandwidth: Example
The following examples shows how Router R1 sends DMZ link bandwidth extended communities to Router
R2 over eBGP peer connection:
R1: sending router
------------------
neighbour 10.3.3.3
remote-as 2
ebgp-send-extcommunity-dmz
address-family ipv4 unicast
route-policy pass in
route-policy pass out
!
R2: Receiving router
--------------------
neighbor 192.0.2.1
remote-as 3
ebgp-recv-extcommunity-dmz
address-family ipv4 unicast
route-policy pass in
!
route-policy pass out
!
The following is a sample configuration that displays the DMZ link bandwidth configuration in the sending
(R1) router:
RP/0/RP0/CPU0:router)# show bgp ipv4 unicast 10.1.1.1/32 detail
Path #1: Received by speaker 0
Flags: 0x4000000001040003, import: 0x20
Advertised to update-groups (with more than one peer):

Advertised to peers (in unique update groups):
