Configure Replication

1. Enter the global configuration mode.
   

   device# configure terminal
   device (config)# 

2. Create an egress port.
   

   device (config)# egress name

3. Associate the egress ports or LAG with the egress.
   

   device(config-egress)# egress name
   device(config-egress)# precedence number interface port-channel number

4. Configure the egress group within the route-map.
   

   device(conf)# route-map name permit sequence_number
   device(conf-route-map)# set egress-group name

5. Add an egress object to the egress-group, pointing to a LAG.
   

   device (conf-egress-group)# set egress egress-one

   Traffic is forwarded to the LAG and load balanced within the LAG.
6. Add or remove LAG members as required for load balancing.
   

   device# configure terminal 
   device(config)# interface ethernet 1/1 
   device(config-if)# channel-group 1 mode on
   device(config-if)# no channel-group 1

7. Add another egress object to the egress-group.
   

   device (config)# egress-group name
   device(conf-egress-group)# set egress egress-two

   Traffic is replicated and copies are sent to both egress objects.
8. Create the required listener policy.
   

   device (config)# listener-policy { name sequence-id }

9. Add the required listener policy.
   

   device (conf-egress-group)# set listener-policy name

   The listener policy is applied based on the egress object.
10. Configure the encap type.
    

    encap-type gre

11. Add a new egress object with single port to the egress-group.
    

    device (config)# egress-group name
    device (conf-egress-group)# egress egress-three

    This egress object receives plain frames unmodified.

Example

egress toolA

# conf 
(conf)# egress egressA 
(conf-egress)# precedence 10 interface ethernet 0/10 
(conf-egress)# set encap encap-100 
(conf-egress)# set listener-policy lp-100

egress toolB

# conf
(conf)# egress egressB
(conf-egress)# precedence 10 interface ethernet 0/20
(conf-egress)# set encap encap-200
(conf-egress)# set listener-policy lp-100

egress toolC

# conf
(conf)#egress egressC
(conf-egress)# precedence 10 interface ethernet 0/30
(conf-egress)# set encap encap-100
(conf-egress)# set listener-policy lp-200

egress-group (replication)

# conf
(conf)# egress-group groupABC
(conf-egress-group)# egress egressA
(conf-egress-group)# egress egressB
(conf-egress-group)# egress egressC

route-map

(conf)# route-map rmap1 permit 10
(conf-route-map)# match ipv4-acl ipv4_acl1
(conf-route-map)# set egress-group groupABC

ingress-group

device(config)# ingress-group group-1  
device(config-group-1)# set route-map rmap1

show egress-group

device# show egress-group groupABC 
    Name : groupABC 
     Description : - 
          egress : egressA  
          egress : egressB 
          egress : egressC
