Support Service and Solution Combinations

The following considerations apply when Ethernet tunnels are configured under a VPLS
service:

Only ports in access or hybrid mode can be configured as eth-tunnel path members. The
member ports can be located on the same or different IOMs or MDAs.
Dot1q and QinQ ports are supported as eth-tunnel path members.
The same port cannot be used as member in both a LAG and an Ethernet-tunnel.
A mix of regular and multiple eth-tunnel SAPs and PWs can be configured in the same
BVPLS.
Split horizon groups in BVPLS are supported on eth-tunnel SAPs. The use of split horizon
groups allows the emulation of a VPLS model over the native Ethernet core, eliminating
the need for P-MSTP.
STP and MMRP are not supported in a BVPLS using eth-tunnel SAPs.
Both PBB ELINE (Epipe) and ELAN (IVPLS) services can be transported over a BVPLS
using Ethernet-tunnel SAPs.
MC-LAG access multi-homing into PBB services is supported in combination with
Ethernet tunnels:
→ MC-LAG SAPs can be configured in IVPLS or Epipe instances mapped to a BVPLS
that uses eth-tunnel SAPs
→ Blackhole Avoidance using native PBB MAC flush/MAC move solution is also
supported
Support is also provided for BVPLS with P-MSTP and MMRP control plane running as
ships-in-the-night on the same links with the Ethernet tunneling which is mapped by a
SAP to a different BVPLS.
→ Epipes must be used in the BCBs to support scalable point-to-point tunneling between
the eth-tunnel endpoints when management VPLS is used.
The following solutions or features are not supported in the current implementation and
are blocked:
→ Capture SAP
→ Subscriber management
→ BSX
→ Eth-tunnels usage as a logical port in the config>redundancy>multi-
chassis>peer>sync>port context
