In the following example of the set mgc list command, if the MGC with the IPv4 address 135.6.8.99 and IPv6 address 2001:db8::370:7334 is available, that MGC becomes the Branch Gateway’s MGC. If that server is not available, the Branch Gateway searches for the next MGC on the list, and so on.

Gxxx-001(super)# set mgc list 135.6.8.99+2001:db8::370:7334,135.34.54.2,2001:db8::1428:5
