You can find an example of the generation of a tunnel router processor in section "Local and remote IPv6, and IPv6 systems accessible via an IPv4 tunnel (LAN6#1)".

<processor-name 1..8>
Name of the processor
NAME-OF-ROUTE=
Using NAME-OF-ROUTE, you specify the name of the route that is defined as the new (additional) route to the processor.
NAME-OF-ROUTE= *default
The name of the processor is used as the route name.
NAME-OF-ROUTE=<rout-name 1..8>
Name of the route defined as the new (additional) route to the processor.
If there is already an existing route to the processor with the same route name as the name of the processor, the NAME-OF-ROUTE operand must be specified.
GEN=REMOTE
A remote processor is generated and activated.
PROFIL=(TCP,IPV6)
The Layer 4 protocol TCP and the Layer 3 protocol IPv6 are used on the route to the processor.
I6-ADDRESS=...
With I6-ADDRESS, you specify the IPv6 address of the processor.
I6-ADDRESS= *default
The IPv6 address of the processor is taken from the processor file or the socket host file.
I6-ADDRESS=<c-string 1..45>
With I6-ADDRESS, you specify the IPv6 address of the processor.
OWN-I6-ADDRESS=...
In OWN-I6-ADDRESS you enter the local IPv6 address at which the host can be addressed at this LAN together with the IPv6 prefix length.
OWN-I6-ADDRESS= *default
The known IPv6 address of the host is used as the local IPv6 address.
OWN-I6-ADDRESS=<c-string 1..49>
Local IPv6 address at which the host can be addressed at this LAN together with the IPv6 prefix length.
(Syntax: IPv6 address/IPv6 prefix length)
SOKHOST=...
In SOKHOST you enter the processor’s socket host name.
SOKHOST= *default
The processor name is used as the socket host name.
SOKHOST=<c-string 1..32> / <sokhost-name 1..32>
Socket host name of the processor.
CONFIGURATION=...
The operand specifies whether or not the network configuration for the processor can be modified using the routing protocol function. The specification is only possible for processors accessed by routes with the L3 profile IP, IPv6 or INTF.
CONFIGURATION=UPDATE
Route modifications resulting from routing protocol functions lead to modifications to the BCAM routing tables and remain effective for this BCAM session.
CONFIGURATION=PRIMARY
Route modifications resulting from routing protocol functions are canceled. The original configuration information is used again.
CONFIGURATION=NO
Route modifications resulting from routing protocol functions are not permitted.
TUNNEL-ROUTE=<rout-name 1..8>
You use TUNNEL-ROUTE to specify the route name of the router (with L3 profile IP) via which the route leads to the processor.
On the way to the tunnel, IPv6 is transported piggyback via IPv4. Tunnel routes must be capable of an NSDU length of at least 1280 bytes.
HOST=...
Using HOST, you specify the name of the host from which the route to the processor leads
HOST= *default
The name of the default host (host name from the DCSTART or DCOPT command) is used as the host name.
HOST=<host-name 1..8>
Name of the host from which the route to the processor leads.
LINE=...
Using LINE, you specify the name of the line which is used as the connection to the router (processor), specified using ROUTE, for the route to the processor.
LINE= *default
One of the existing lines to the router is selected at random as the line which is used as the connection to the router, specified using ROUTE, for the route to the processor. If more than one line to the router exists, the LINE operand must be specified.
LINE=<line-name 1..8>
Name of the line, which is used as the connection to the LAN node, specified using ROUTE, for the route to the processor.
MAXTSDU=<integer 4096..65530>
Using MAXTSDU, you specify the maximum receive message length of the processor.
Default: 4096
ROUTE-SELECT=...
ROUTE-SELECT determines how transport connections are distributed over the routes to a processor when a connection is being established.
ROUTE-SELECT=*SEQUENTIAL-WITH-RETRY
Sequential distribution (i.e. the next route is not tried until the maximum number of transport connections for the previous route has been reached) with repeat selection if the selection of a route fails.
ROUTE-SELECT=*SEQUENTIAL
Sequential distribution (i.e. the next route is not tried until the maximum number of transport connections for the previous route has been reached) without repeat selection if the selection of a route fails.
ROUTE-SELECT=*BALANCED-WITH-RETRY
Balanced distribution of transport connections across the routes with repeat selection if the selection of a route fails.
ROUTE-SELECT=*BALANCED
Balanced distribution of transport connections across the routes without repeat selection if the selection of a route fails.
ROUTE-SEQUENCE-NUM=0/<integer 0..99>
Route number for route selection. Determines the sequence of routes during route selection.
Default value: 0
MAP=...
Using MAP, you specify whether the name of the processor may be used in a mapping definition (BCMAP command).
MAP=YES
The name of the processor may be used in a mapping definition (BCMAP command).
MAP=NO
The name of the processor may not be used in a mapping definition (BCMAP command).
ADM=...
Using ADM, you specify the administration type for the processor.
ADM=BCAM
The processor is administered using BCAM.
ADM=UNKNOWN
The administration type for the processor is unknown.
ACT=...
You use ACT to specify whether the processor is activated.
ACT=YES
The processor is activated.
ACT=NO
The processor is not activated.
LINK-DOWN=...
The operand specifies whether or not the transport connections assigned to the route are to be shut down in the event of a route failure.
LINK-DOWN=KEEP-CONNECTION
In the event of a route failure, the transport connections assigned to this route are not shut down.
LINK-DOWN=DISCONNECT
In the event of a route failure, all transport connections assigned to this route are shut down.
Command logging
For reasons of compatibility, positive acknowledgments are supplied in news BCA0763, and negative acknowledgments in news BCA0762, followed by the message NBR0740. In addition, for positive acknowledgments, the messages BCA083E, BCA083F and BCA0620 may also appear.
A description of the error messages that may be issued during command processing is provided in the table below.
