The GateD Interactive Interface (GII) provides an interactive interface to a running GateD daemon which can be used to query internal gated variables. This interface, which is implemented like any other protocol in GateD, accepts telnet connections to port 6116 (C.f. [RFC 854] for a description of the telnet protocol), and after user identification, answers any query sent as ascii commands. The commands include querying about the memory, routing table, interface list, and other internal parameters.
GII will identify the user by using the Unix password of the gii ID of the system. In other words,
when using the GII interface, one must creat a 'gii'account and set up its password that will be
used when connecting to the GII.
Users open a telnet connection to the machine running GateD, on TCP port 616. They identify
themselves using a simple password scheme, and get the GateD prompt. The GII is then ready to
accept queries. Here is an example of such a session:
(lpj@belix: 53) telnet radb2.ra.net 616
Trying 198.108.0.9...
Connected to radb2.ra.net.
Escape character is '~]'.

GateD> sh ip
100 HELP: The possible subcommands are:
100 route [x.x.x/len]: Show info about IP routes
100 walkup x.x.x/len: Show less specific routes
100 walkdown x.x.x/len: Show more specific routes

The top level command help provides a list of available commands. Commands may be followed
by subcommands. To get help about the subcommand, just type the main command without
subcommand. GII will display a list of available subcommands. Commands may be abbreviated
when no confusion is possible.
kernel
show the kernel support.
interface [name | address]
show interface status.
memory
show the memory allocation.
ip [pimsm | igmp]
show info about ip protocol The options to show under IP protocol include the pim-sm commands and the igmp commands:
ip pimsm [bsr | crp | routeall | rpset | timeout | [interface address]]ip igmp groups
task
show list of active tasks.
dvmrp [mfc | targets]
show info about dvmrp protocol.
ospf [global | [ interface address] | [area [id]]
show info about ospf protocol.
timer
show list of timers.
bgp [summary | [peeras as_no] | [aspath regexp]]
The following command will display parameters related to the internal structure of GateD:
show version
shows the version of the running GateD.
show kernel
shows the type of kernel of the host, including what features are support (Reject routes, Multicast, UDP chechsums, etc...).
show memory
shows the memory usage, divided by memory block structures.
show task
shows the running tasks in GateD.
show timers
shows list of timers.
The following command will display parameters related to the interfaces:
show interface [name|index]
Without parameter, this command lists all the interfaces of the system. If one interface name or index is given as an argument, all the parameters concerning this interface are displayed.
The following command will display parameters related to the routing table:
show ip route [x.x.x/len]
Without parameter, this command prints the size of the IP routing table. With an argument, which must be a prefix number and mask length, it displays complete information about the given route, like number of announcements, next hop, AS path, active route, etc...
show ip walkup x.x.x/len
Lists all the routes that are less specific than x.x.x/len, i.e. all the components of the aggregate x.x.x/len. show ip walkdown 0/0 will display the whole routing table. ^C can be used to stop the listing.
show ip rpf <source-address>
Displays how IP multicast routing does Reverse Path Forwarding. Since GateD can RPF from multiple routing tables (i.e. unicast routing table, DVMRP routing table, or static mroutes), this command tells you where the information is retrieved from
global
shows general ospf options
interface address
shows IP interface status
area [=0]
shows area information
show bgp summary
show bgp peeras [AS number]
show bgp aspath [AS path regexp]
show ip igmp groups
Displays directly connected groups learned via IGMP.
show dvmrp mfc
List all Multicast forwarding cache defined.
show dvmrp targets
Lists all the DVMRP targets (interfaces).
show ip pimsm bsr
Displays BSR status.
show ip pimsm crp
Displays Candidate Rp status.
show ip pimsm interface
Displays PIM-SM interface information.
show ip pimsm neighbor
Displays PIM-SM neighbors discovered.
show ip pimsm routeall
Shows PIM-SM Routing table.
show ip pimsm rpset
Dump RP-SET.
show ip pimsm timeout
Dump all components, timeouts.
quit
to close the GII session.
help - show help screen.
show - queries GateD for current status. See below for parameters.
quit - end your telnet session.
Show is the working command. Syntax: show <parameter> [optional parameters
