VPLS Exceptions on J-Series Services Routers
The VPLS implementation on a J-series Services Router is similar
to VPLS implementations on M-series, T-series, and MX-series routers,
with the following exceptions:
- Services Routers do not support aggregated Ethernet interfaces.
Therefore, aggregated Ethernet interfaces between CE devices and PE
routers are not supported for VPLS routing instances on Services Routers.
- VPLS routing instances on Services Routers use BGP to
send signals to other PE routers. LDP signaling is not supported.
- VPLS multihoming, which allows connecting a CE device
to multiple PE routers to provide redundant connectivity, is not supported
on Services Routers.
- Services Routers do not support BGP mesh groups.
- Services Routers only support the following encapsulation
types on VPLS interfaces that face CE devices: extended VLAN VPLS,
Ethernet VPLS, and VLAN VPLS. Ethernet VPLS over ATM LLC encapsulation
is not supported.
- Virtual ports are generated dynamically on a Tunnel Services
PIC on some Juniper Networks routing platforms. Services Routers do
not support Tunnel Services modules or virtual ports.
- The VPLS implementation on Services Routers does not support
dual-tagged frames. Therefore, VLAN rewrite operations are not supported
on dual-tagged frames. VLAN rewrite operations such as pop-pop, pop-swap,
push-push, swap-push, and swap-swap, which are supported on M-series
and T-series routing platforms, are not supported on Services Routers.
- Firewall filters for VPLS are not supported.
