Description
ARDA (Aqua Router DAemon) – part of the routing package, which includes OSPF and ARIP modules. Performs a coordinator and integrator functions for the routing protocols management. ARDA module realize all manipulations with system routing tables.

Parameter | Description |
---|
end | Goes back from the current mode to the basic (ARDA), keyboard shortcut Ctrl+C can also be used. | exit | Exit from ARDA CS, keyboard shortcut Ctrl+D can also be used.
| help | Displays the whole command list for the current mode. | show | Allows to review current ARDA configuration. "access-list" – displays access lists content. - "memory" – a memory statistic.
- "all", "lib", "ospf" and "rip" – specify values types to be shown. If not specified, data will be displayed for all types, same as the "all" parameter.
- "arda client" – displays ARDA client information.
"route" – displays a routing table. Additional parameters allow to filter displayed routes. If not specified the whole table is shown. "connected" – directly connected routes. "kernel" – routes created by the kernel, except for the default route. "ospf" – routes advertised by the OSPF router. "rip" – routes retransmitted from the RIP protocol. "static" – static routes. "summary" – summary routes. "supernets-only" – connections from aggregated networks only.
"interface" – displays information about network interfaces. "ip forwarding" – shows IP routing state.
"running-config" – shows a current ARDA configuration.
- "show thread cpu" – shows current cpu load. Filters can be used to display specific data (rwtex).
"version" – shows ARDA version.
| configure | Allows to enter the "ARDA config" mode
| ARDA config mode | access-list | Access lists are used in the ARDA configuration as filters, in addition, they are also used to set the matching conditions in the route map configuration. Access lists consist of an operators set. Each operator consists of a IP addresses range (matching conditions) and resulting action: "deny" or "permit". The IP addresses range is set in "<value> <mask>" form. The object to be filtrated has its basic parameter in the same format (IP address, subnet etc). To make a decision whether the object corresponds with a list, each operator from the list is consequently applied to the object basic parameter until this parameter satisfies the condition. When a right condition is met, the decision is made according to the record in the operator command. While configuring, the operators are added to the end of the list. Thus, when filtering, the sequence of viewing access list operators is determined only by the sequence of their addition. There are three access lists type in the ARDA module. - Standard – is identified by the 1-99 numbers in the standard range or 1300-1999 in the extended and is used to evaluate one filtration objects parameter.
- Extended – is identified by the 100-199 numbers in the standard range or 2000-2699 in the extended and is used to evaluate one filtration objects parameter (ex. source IP address and destination IP address).
- Nominate – is similar to the standard, but is identified by a name. In addition, operators are configured in a "<value>/<mask length>" format.
For more information about managing access lists parameters see the "Access list" subsection. | interface IFNAME | Entering the "config-if" mode. "IFNAME" – an interface to configure. - "bandwidth <1-10000000>" – limits bandwidth, allowable values are in range 1...10000000 Kbps.
- "description" – network interface symbolic description.
- "link-detect"– allows the use physical layer messages about the network interface status. Otherwise, the link presence or absence is determined by exceeding the time limit.
| route A.B.C.D/M (A.B.C.D|INTERFACE|null0) (blackhole|reject) (<1-255>) | Allows to configure static routes within an ARDA module. Note |
---|
| These static routes will only be applied if the ARDA module is active. |
- "A.B.C.D/M" – source IP address.
- "A.B.C.D|INTERFACE|null0" – the gateway IP address / the network interface name through which the connection is established. If "null0" interface is specified, traffic will be destroyed.
- "blackhole" – traffic is destroyed without notifying the sender.
- "reject" – traffic is destroyed, sender receives an ICMP notification.
- "<1-255>" – route metric.
| stop (daemon|clear) | Stops ARDA module: - "daemon" – stops the router.
- "clear" – the router will clear its system configuration part before quitting.

In case of nominate list, identifier is an arbitrary characters combination. Values range is specified in "<value> <mask>" form. For value 0.0.0.0 there is a key word "any".
Examples
In the nominate list, specify the decision to discard a packet for the "192.168.110.0"..."192.168.110.255" IP addresses range. Value "192.168.110.0/24" should be specified and the decision to accept packets from all other addresses. Code Block |
