Virtual Interface Bundling on the CiscouBR10-MC5X20S/UBPECisco IOS Release 12.3(13a)BC introduces support for virtual interface bundling on the Cisco
uBR10012 universal broadband router and the Cisco uBR10-MC5X20S/U Broadband Processing
Engine (BPE), and the Cisco uBR7246VXR router.
In prior Cisco IOS releases, cable interface bundling was limited to physical interfaces as master or slave
interfaces, and show commands did not supply bundle information.
Virtual interface bundling removes the prior concepts of master and slave interfaces, and introduces
these additional changes:
•Virtual interface bundling uses bundle interface and bundle members instead of master and slave
interfaces.
•The virtual bundle interface is virtually defined, as with IP loopback addresses, for example.
•Virtual interface bundling supports bundle information in multiple show ip interface commands.
Virtual interface bundling prevents loss of connectivity on physical interfaces should there be a failure,
problematic online insertion and removal (OIR) of one line card in the bundle, or erroneous removal of
configuration on the master interface.
Virtual interface bundling supports and governs the following Layer 3 settings for the bundle member
interfaces:
•IP address
•IP helper-address
•source-verify and lease-timer functions
•cable dhcp-giaddr (The giaddr field is set to the IP address of the DHCP client.)
•Protocol Independent Multicast (PIM)
•Access control lists (ACLs)
•Sub-interfaces
