26.1. IPRTR resource

26.1. IPRTR resource
	Chapter 26. IPRTR - IP Router

The IPRTR (IP Router) resource is used within the Abilis CPX to route IP datagrams between LAN and WAN ports.

IP Datagram transport on LAN is carried out using Ethernet or Token Ring protocols.

IP Datagram transport on WAN is carried out using X.25 resource (obsolete) or non-X.25 resources (LAPB, IP Tunnel or PPP links).

26.1.1. IPRTR resource parameters

Use the following command to display the parameters of the resource. By typing d p iprtr ? command it's possible to display the meaning of all the parameters.

Meaning of the most important parameters:

R-ID: It shows the Router ID address [AUTO: it's the default value and it's obtained considering the first IP resource of the homonym table, whose address is not 0.0.0.0; 1-126.x.x.x, 128-223.x.x.x: it's used a specific IP, Ip-nnn].
NAT: It indicates the side of the IPRTR when remote hosts connect to R-ID IP address. This information is required by NAT in order to determine if the IP address must be translated or not. This parameter can be set only when R-ID is not set to AUTO [NO: NAT is not configured; INSIDE: the R-ID address is in the INSIDE IP resource; OUTSIDE: the R-ID address is in the OUTSIDE IP resource, VPN: the R-ID address is in the VPN IP resource, DMZ: the R-ID address is in the DMZ IP resource].
maxroute: Maximum number of routings in the routing table [100..10000].
DFTTTL: Default TTL value when transport layer doesn't provide one [1..255].
ps: Packet size [16..2048 bytes].
DEF-LOCAL-AD: Default administrative distance for local-connected routes [0..255].
DEF-STATIC-AD: Default administrative distance for static routes [0..255].
DEF-OSPF-AD: Default administrative distance for OSPF routes [0..255].
DEF-RIP-AD: Default administrative distance for RIP routes [0..255].
ACL: Access list activation mode [NO, YES].
ACLBYPASS: Source/destination IP address that bypasses the Access list [*, #, 1-126.x.x.x, 127.0.0.1, 128-223.x.x.x].
ACL-FIREWALL: Enable/disable Access lists using 'Firewall' list [NO, YES] When NO, Access list with PR:0 and PR:1 are ignored. When YES, Access list with PR:0 and PR:1 are used.
COS: Enable/Disable class-of-service management [DISABLED, ENABLED].
COSDFT: Class-of-service Default value [HIGH, NORMAL, LOW].
COSBALANCE: Class-of-service balancing activation [NO, YES].
NORMRATE: NORMAL vs. HIGH class-of-service balancing percentage [0..100].
LOWRATE: LOW vs. NORMAL class-of-service balancing percentage [0..100].
PPP-DNS-PRI: Primary DNS provided by local PPPs to remote PPPs [0.0.0.0, 1-126.x.x.x, 127.0.0.1, 128-223.x.x.x].
PPP-DNS-SEC: Secondary DNS provided by local PPPs to remote PPPs [0.0.0.0, 1-126.x.x.x, 127.0.0.1, 128-223.x.x.x].

The following command allows the administrator to change the configuration of the resource:

s p iprtr parameter:value...

	Caution
	To activate the changes made on the upper case parameters, execute the initialization command init res:iprtr; while to set act the changes made on the lowercase parameters a save conf and an Abilis restart are required (i.e. With warm start command).
