TitleHow to configure VPLS with ESRP redundancy
Objective
Enable VPLS redundancy with ESRP to allow only one PE switch per Data Center to become designated forwarder for specific L2 transparent service.
Environment
  • Summit
  • BlackDiamond
  • EXOS
Procedure
Example Scenario

Topology with VPLS + ESRP Redundancy

PE1 and PE2 Configuration Example
  • Create the service_vlan with tag 1001
  • Create and configure all /30 link vlans between PE's and between PE's and P's devices 
  • Create and configure the loopback vlan for all PE's devices
  • Configure and enable OSPF for all vlans except for service_vlan
  • Create and configure MPLS with LDP for all vlans except for service_vlan

configure mpls add vlan <link_vlan> 
enable mpls vlan <link_vlan>
enable mpls ldp vlan <link_vlan> 
configure mpls add vlan <loopback_vlan> 
enable mpls vlan <loopback_vlan>
enable mpls ldp vlan <loopback_vlan>

configure mpls lsr-id <loopback_IPaddress>
enable mpls protocol ldp
enable mpls 

  • Create and configure ESRP Control Vlan
create vlan <esrp_Control_Vlan>
config vlan <esrp_Control_Vlan> tag 1001
config vlan <esrp_Control_Vlan> add ports 1,2 tagged  
  • Create, configure and enable ESRP domain
create esrp <esrp_Domain> type vpls-redundancy
configure esrp <esrp_Domain> domain-id <number>
configure esrp <esrp_Domain> add master <esrp_Control_Vlan>
enable esrp <esrp_Domain>
  • ​Create and configure VPLS Tunnel/PW
create l2vpn vpls tunnel1 fec-id-type pseudo-wire  <pwid>
configure l2vpn vpls tunnel1 add service vlan <service_Vlan>
configure l2vpn vpls tunnel1 add peer 192.168.200.3 core full-mesh
configure l2vpn vpls tunnel1 add peer 192.168.200.4 core full-mesh
configure l2vpn vpls tunnel1 add peer 192.168.200.5 core full-mesh
configure l2vpn vpls tunnel1 add peer 192.168.200.6 core full-mesh
 
  • Configure VPLS Tunnel to use ESRP redundancy
configure l2vpn vpls tunnel1 redundancy esrp <esrp_Domain>
 
  • Check ESRP state for each PE device
show esrp
 
  • Check VPLS state for each PE device
show vpls
 
The configuration between PE5 and PE6 and between PE3 and PE4 will be the same. The difference in the configuration compared to PE1 and PE2 will be link_vlan configuration, loopback_IPaddressesrp_Domain, domain-id and peer IP address.

P Devices Configuration Example
  • Create all /30 link vlans between P's devices
  • Create the loopback vlan for all P's devices
  • Configure and enable OSPF for all vlans
  • Configure and enable MPLS/LDP for all vlans:

configure mpls add vlan <link_vlan>
enable mpls vlan <link_vlan> 
enable mpls ldp vlan <link_vlan> 
configure mpls add vlan <loopback_vlan> 
enable mpls vlan <loopback_vlan>
enable mpls ldp vlan <loopback_vlan>
configure mpls lsr-id <loopback_IPaddress>
enable mpls protocol ldp
enable mpls
