How to safely migrate circuits on VSX NGX R65 in a VRRP configuration from one interface to anotherN/A
Migrating circuits from one circuit to another, in a VSX configuration.
This solution is specifically written for VSX NGX R65 in a VRRP configuration, but it could work for other flavors of VSX. If you need to migrate a circuit from an MLT interface to another physical interface (due to an NPM upgrade) there are some specific steps to be followed; especially when the system is running in dual-box HA (VRRP).
Modifying VRRP and remapping the circuits manually in the XOS CLI does not work. The configuration file is pushed by VSX, which would cause local.vsall to not be in sync with the configuration on the CPM.
This is how a group interface config might look like in initial stage:
Special care must be taken not to remove the VRRP config or circuits associated to the warp links or virtual routers. Removing these will result in the configuration not being generated properly, and a full cleanup of VSX may be needed.
4.Configure the new interface with the appropiate circuit attached to it.
