Configure Multiple Anycast IP

About this task

You can provide multiple anycast IP address per tenant ctag when you create or update an EPG, add ctag-range, add VRF, and add or delete anycast IP. The multiple anycast IP address is configured under the interface Ve of the switching hardware.

Procedure

  1. To configure multiple anycast IP when you create an EPG, run the following command: 
    efa tenant epg create --name <epg-name> --tenant <tenant-name>

           --switchport-mode <mode>
	    --port <port-list> --po <po-list>

          --ctag-range <ctag-range> 
          --vrf <vrf-name>
	          
	   --anycast-ip <value> --anycast-ip <value> 
	   --anycast-ipv6 <value> --anycast-ipv6 <value>
  2. To configure multiple anycast IP when you update an EPG, run the following command: 
    efa tenant epg update --name <epg-name> --tenant <tenant-name>  
 	         
	          --operation vrf-add | ctag-range-add |anycast-ip-add | anycast-ip-delete| 
	          --ctag-range <ctag-range> --vrf  <vrf-name>

   	       --anycast-ip <value> --anycast-ip <value>
	          --anycast-ipv6 <value> --anycast-ipv6 <value>

Example

Example:

Multiple anycast IP configuration example when you create an EPG:

efa tenant epg create --name e1 --tenant tenant11 --po po1 --switchport-mode trunk-no-default-native --vrf v1 --ctag-range 101-102  --anycast-ip 101:1.1.1.254/24 --anycast-ip 101:2.1.1.254/24 --anycast-ip 101:3.1.1.254/24 --anycast-ipv6 101:1::1/124 --anycast-ipv6 102:2::1/124
