Describes a feature that allows selective forwarding of ether-types across URWB networks in MPLS Layer 2 mode.
Layer 2 mesh transparency is a feature that allows selective forwarding of specific ether-types across URWB networks in MPLS Layer 2 mode.
Reserved ether-types
This list of reserved ether-types cannot be configured:
| Ether-type range |
Forwardable |
Additional information |
|---|---|---|
| 0x0000 – 0x05FF |
User-configurable |
Ethernet-I frames. STP and CDP are subject to other configuration options. |
| 0x0800 |
Yes |
IPv4 |
| 0x0806 |
Yes |
ARP (IPv4) |
| 0x0900 – 0x09FF |
No |
URWB signaling protocols |
| 0x8100 |
Yes |
IEEE 802.1Q VLAN encapsulation |
| 0x8847 – 0x8848 |
No |
MPLS |
| 0xFFFF |
No |
IANA reserved |
These functionalities are supported using the URWB data plane mesh network when used in MPLS Layer 2 mode:
-
Ether-types present in URWB network are detected and reported automatically.
-
You can add and remove ether-types from the allowlist.
-
You can configure full transparency to enable all Layer 2 protocols easily.
-
The feature supports both CLI and GUI.
