12.6 L2VPN Kompella mode configuration
Unlike Martini mode, where all operation is done by the LDP, in this mode the LDP does only operate with
transport labels. Autodetection (not typical of LDP signaling), and the construction of a pseudowire connection
is entrusted to BGP.
12.6.1 L2VPN VPLS configuration algorithm
Step Description Command Keys
1 Configure the LDP (see section LDP
configuration).
2 Create a network bridge in the system
without specifying an IP address (see
section Bridge configuration).
3 Create VPLS domain in the system and
switch to the VPLS domain
configuration mode.
esr(config-l2vpn)# vpls <NAME> <NAME> — name of the p2p
service, set by the string of up
to 31 characters.
4 Enable VPLS tunnel. esr(config-l2vpn-vpls)# enable
5 Add bridge domain. esr(config-l2vpn-vpls)# bridge-
group <ID>
<ID> — bridge domain
identifier, specified in the range
[1..250].
6 Switch to the autodiscovery bgp
configuration context.
esr(config-l2vpn-vpls)#
autodiscovery bgp
7 Specify route distinguisher for the given
VPLS instance.
esr(config-bgp)# rd <RD> <RD> – Route distinguisher
value, specified in one of the
following forms:
<ASN>:<nn> — where
<ASN> may take values
[1..65535], nn may take
values [1..65535];
<ADDR>:<nn>— where
<ADDR> specified as
AAA.BBB.CCC.DDD/EE,
AAA-DDD may take
values [0..255], nn may
take values [1..65535];
<4ASN>:<nn>— where
<4ASN> may take values
[1..4294967295], nn may
take values [1..65535];
