Change the Default Gateway of a TPVM

Use this procedure to change the default gateway of a TPVM. This procedure has no impact on the functioning of EFA high-availability mode.

The gateway IP address must be in the same subnet as one of the subinterfaces that are created in EFA.
Perform this procedure on both nodes where EFA is deployed, to avoid a loss of EFA functionality.
Perform this procedure with caution. EFA and SLX-OS do not validate reachability of the gateway during this operation.
Vital services, such as DNS, NTP, and LDAP, must be reachable from the new gateway.

Add static IP addresses to the subinterface.
You can assign a maximum of one pair of static IP addresses. Only one subinterface at a time can have static IP addresses.
```
efa mgmt subinterface staticip --name <sub-int-name> --ip1 <ip-addr> 
--ip2 <ip-addr>
```

Change the gateway of the standby TPVM.

efa inventory device execute-cli --ip <standby-slx-ipaddr> 
--command "tpvm TPVM,interface management ip <standby-tpvm-ipaddr> 
gw <new-gateway-ipaddr>" --config

Change the gateway of the active TPVM.

efa inventory device execute-cli --ip <active-slx-ipaddr> 
--command "tpvm TPVM,interface management ip <active-tpvm-ipaddr> 
gw <new-gateway-ipaddr>" --config
