Change the Default Gateway of a TPVM

You can change the default gateway of a TPVM.

About this task

Follow this procedure to change the default gateway of a TPVM for the IPv4 IP-Stack.

You can use this procedure for Dual IP-Stack type with Dual static IP configuration. For more information, see Configure Static IP Addresses for Management Sub Interfaces.

This procedure does not affect the functioning of XCO high-availability mode.

The gateway IP address must be in the same subnet as one of the subinterfaces that are created in XCO.
To configure a default gateway for the subinterface subnet, use only static IPv4 addresses.
Perform this procedure on both nodes where XCO is deployed, to avoid a loss of XCO functionality.
Perform this procedure with caution. XCO 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.

Procedure

Add static IP addresses to the sub interface.
You can assign a maximum of one pair of static IP addresses. Only one sub interface 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
