MVR with EAPS

Since MVR is designed with a Layer 2 ring topology in mind, it is strongly recommended that it should be deployed with EAPS. The MVR plus EAPS combination provides a superior solution for any triple play network, where the service provider intends to provide data, voice, and video services. EAPS is a proven solution for providing sub-second SONET-like protection to Layer 2 rings. For more detail on EAPS refer to EAPS.

Consider a typical EAPS topology in the following figure, where 3 VLANs on the core ring serve various clients on each switch. To provide video service, one of the VLANs on the EAPS ring is designated as a multicast VLAN. MVR is enabled only on this VLAN (mcastvlan). V1 is the control VLAN, and V2 is another protected VLAN. A router serving the multicast feed would typically run PIM on mcastvlan, to support the static and dynamic IGMP membership on the VLAN.

The following is a typical configuration for the router and switches.

Router1:

create vlan mcastvlan
configure mcastvlan add port 1:1
create vlan server
configure server add port 1:2
configure mcastvlan ipaddress 10.1.1.1/24
configure server ipaddress 11.1.1.1/24
configure igmp snooping mcastvlan port 1:1 add static group 239.1.1.1
enable ipforwarding
enable ipmcforwarding
configure igmp snooping leave-timeout 2000
configure pim add vlan all
enable pim

Switch1:

create vlan mcastvlan
create vlan v1
create vlan v2
create vlan vlan2
configure vlan vlan2 add port 1:3
configure vlan vlan2 ipaddress 10.20.1.1/24
configure mcastvlan tag 20
configure mcastvlan add port 1:1,1:2 tag
configure mvr add vlan mcastvlan
configure vlan v1 tag 30
configure v1 add port 1:1,1:2 tag
configure vlan v2 tag 40
configure v2 add port 1:1,1:2 tag

create eaps e1
configure eaps e1 mode transit
configure eaps e1 add control vlan v1
configure eaps e1 add protect vlan mcastvlan
configure eaps e1 add protect vlan v2
configure eaps port primary port 1:1
configure eaps port secondary port 1:2
enable eaps
enable mvr

Switch3:

create vlan McastVlan
create vlan v1
create vlan v2
configure mcastvlan tag 20
configure mcastvlan add port 1:2,1:3 tag
configure mcastvlan add port 1:1
configure mvr add vlan mcastvlan
configure vlan v1 tag 30
configure v1 add port 1:2,1:3 tag
configure vlan v2 tag 40
configure v2 add port 1:2,1:3 tag

create eaps e1
configure eaps e1 mode master
configure eaps e1 add control vlan v1
configure eaps e1 add protect vlan mcastvlan
configure eaps e1 add protect vlan v2
configure eaps port primary port 1:3
configure eaps port secondary port 1:2
enable eaps
enable mvr

Note

In this example, Switch3 is the EAPS master, but any of the other switches in the ring could have been configured as the master.
