DMZ Link Bandwidth for Unequal Cost Recursive Load Balancing
The demilitarized zone (DMZ) link bandwidth for unequal cost recursive load balancing feature provides
support for unequal cost load balancing for recursive prefixes on local node using DMZ link bandwidth. Use
the dmz-link-bandwidth command in BGP neighbor configuration mode and the bandwidth command in
interface configuration mode to The unequal load balance is achieved.
When the PE router includes the link bandwidth extended community in its updates to the remote PE through
the Multiprotocol Interior BGP (MP-iBGP) session (either IPv4 or VPNv4), the remote PE automatically does
load balancing if the maximum-paths command is enabled.
Unequal cost recursive load balancing happens across maximum eight paths only.Note
