Step Description Command Keys
5 Connect sub interface, qinq interface, 
L2GRE tunnel or L2TPv3 tunnel with the 
network bridge. Connected interfaces/
tunnels and network bridges 
automatically become participants of 
the shared L2 domain (optional).
esr(config-if-gi)# bridge-group 
<BRIDGE-ID>
esr(config-if-l2tpv3)# bridge-group 
<BRIDGE-ID>
<BRIDGE-ID> – bridge 
identification number, takes 
values in the range of:
for ESR-10/12V(F)/
14VF/15 – [1..50];
for 
ESR-20/21/30/100/200 
– [1..250];
for 
ESR-1000/1200/1500/1
511/1700/3100/3200 – 
[1..500].
6 Connect the current network bridge 
with VLAN. All interfaces and L2 
tunnels that are members of the 
assigned VLAN are automatically 
included in the network bridge and 
become members of the shared L2 
domain (optional)
esr(config-bridge)# vlan <VID> <VID> – VLAN identifier, set in 
the range of [1..4094].
7 Specify the size of MTU packets that 
can be passed by the bridge (optional; 
possible if only VLAN is included in the 
bridge).
MTU above 1500 will be active only 
when using the 'system jumbo-frames' 
command.
esr(config-bridge)# mtu <MTU> <MTU> – MTU value, takes 
values in the range of:
for ESR-10/12V(F)/14VF 
– [552..9600];
for ESR-20/21 – 
[552..9500];
for 
ESR-100/200/1000/120
0/1500/1511/1700 – 
[552..10000]
for 
ESR-1500/1511/1700/3
100 – [552..9190].
Default value: 1500
8 Specify the IPv4/IPv6 address and 
subnet mask for the interface to be 
configured or enable IP address obtain 
dynamically.
esr(config-bridge)# ip address 
<ADDR/LEN>
<ADDR/LEN> – IP address and 
subnet mask length, defined as 
AAA.BBB.CCC.DDD/EE where 
each part AAA-DDD takes 
values of [0..255] and EE takes 
values of [1..32].
For advanced IPv4 addressing 
features see section IP 
addressing configuration.
