Hi guys,
I have tested L2VPN on two VPP,and the L2VPN works well.
But I can't get the effective configuration on 3 vpp. The following is all my
configuration not effective.
Is there anything error in my configuration ? How can I get the effective
configuration?
VPP1 - VPP2 - VPP3
VPP1：
create host-interface name eth4 mac 00:0c:29:4d:af:b5
create host-interface name eth2 mac 00:0c:29:4d:af:a1
set interface state host-eth2 up
set interface state host-eth4 up
set interface ip address host-eth2 14.1.1.1/24
mpls table add 0
set interface mpls host-eth2 enable
create mpls tunnel out-label 33 out-label 53 via 14.1.1.2 host-eth2 l2-only
set interface state mpls-tunnel0 up
create bridge-domain 1
set interface l2 bridge mpls-tunnel0 1
set interface l2 bridge host-eth4 1
mpls local-label add non-eos 1023 mpls-lookup-in-table 0
mpls local-label add eos 1053 l2-input-on mpls-tunnel0
set interface mpls host-eth4 enable
VPP3:(packets didn't arrive)

create host-interface name eth5 mac 00:0c:29:19:8e:8a
set interface state host-eth3 up
set interface state host-eth5 up
set interface ip address host-eth3 12.1.1.2/24
VPP2:
(only modify the configuration on VPP2)
