7.7.19.8 Interconnection Node
G.8032 specifies support for a network of interconnected rings. An interconnection node is
an Ethernet ring node which is common to two or more Ethernet ring or to a sub-ring and
an interconnected network. At each interconnection node there may be one or more
Ethernet rings that can be accessed through a single ring port and not more than one
Ethernet ring that is accessed by two ring ports. If the interconnecting node is used to
connect a set of sub-ring to another network, then there is no Ethernet ring accessed by
two ring ports.
The special node for ring interconnection is called an interconnection node, and links be-
tween them are called shared links. To specify the ring port of R-APS interconnection
node, use the following command.
ethernet oam r-aps <1-255> in-
terconnection {east | west}
[{ primary | secondary}]
Specifies the ring port type of R-APS interconnection
node.
primary | secondary: indicates the primary/secondary
node for the minimization of the segmentation.
no ethernet oam r-aps <1-255>
interconnection
Deletes the configured ring ports of R-APS intercon-
nection node.
7.7.19.9 R-APS Virtual Channel
The R-APS virtual channel is the R-APS channel connection between two Interconnecting
nodes of a sub-ring in other Ethernet ring(s) or network(s). For sub-rings, the two inter-
connection nodes may exchanges via a special virtual R-APS channel on the shared links.
Sub-ring with R-APS virtual channel option, R-APS messages are encapsulated and
transmitted over an R-APS virtual channel configured on the major ring.
Sub-ring without R-APS virtual channel option, R-APS messages are terminated at
the interconnection nodes but not blocked at RPL of the sub-ring.
To enable/disable a dedicated VLAN ID, use the following command.
ethernet oam r-aps <1-255> vir-
tual-channel
Configure R-APS channel of sub-ring with R-APS vir-
tual channel.
no ethernet oam r-aps <1-255>
virtual-channel
Configure R-APS channel of sub-ring without R-APS
virtual channel.
