112	AT-WR4500 Series - IEEE 802.11abgh Outdoor Wireless Routers
	RouterOS v3 Configuration and User Guide

bgp-origin(incomplete igp egp) - the origin of the route prefix

bgp-prepend(integer: 0..16) - number which indicates how many times to prepend AS_NAME to

AS_PATH

check-gateway(arp ping; default: ping) - which protocol to use for gateway reachability

distance (integer: 0..255) - administrative distance of the route. When forwarding a packet, the router will use the route with the lowest administrative distance and reachable gateway

dst-address(IP address/netmask; default: 0.0.0.0/0) - destination address and network mask, where netmask is number of bits which indicate network number. Used in static routing to specify the destination which can be reached, using a gateway

0.0.0.0/0 - any network

gateway (IP address) - gateway host, that can be reached directly through some of the interfaces. You can specify multiple gateways separated by a comma "," for ECMP routes

pref-src(IP address) - source IP address of packets, leaving router via this route

0.0.0.0- pref-src is determined automatically

routing-mark(name) - a mark for packets, defined under /ip firewall mangle. Only those packets which have the according routing-mark, will be routed, using this gateway

scope (integer: 0..255) - a value which is used to recursively lookup the nexthop addresses. Nexthop is looked up only through routes that have scope <= target-scope of the nexthop

target-scope(integer: 0..255) - a value which is used to recursively lookup the next-hop addresses. Each nexthop address selects smallest value of target-scope from all routes that use this nexthop address. Nexthop is looked up only through routes that have scope <= target-scope of the nexthop

￿

You can specify more than one or two gateways in the route. Moreover, you can repeat some routes in the list several times to do a kind of cost setting for gateways.

Example

To add two static routes to networks 10.1.12.0/24 and 0.0.0.0/0 (the default destination address) on a router with two interfaces and two IP addresses:

[admin@AT-WR4562] ip route> add dst-address=10.1.12.0/24 gateway=192.168.0.253

[admin@AT-WR4562] ip route> add gateway=10.5.8.1

[admin@AT-WR4562] ip route> print

Flags: X - disabled, A - active, D - dynamic,

C - connect, S - static, r - rip, b - bgp, o - ospf

#	DST-ADDRESS	G GATEWAY	DISTANCE INTERFACE
0	A S 10.1.12.0/24	r 192.168.0.253	Local
1	ADC 10.5.8.0/24		Public
2	ADC 192.168.0.0/24		Local
3	A S 0.0.0.0/0	r 10.5.8.1	Public

[admin@AT-WR4562] ip route>

5.4.3 Policy Rules

Submenu level: /ip route rule

Property Description

action (drop unreachable lookup; default: unreachable) - action to be processed on packets matched by this rule:

drop - silently drop packet

unreachable - reply that destination host is unreachable lookup - lookup route in given routing table dst-address(IP address mask) - destination IP address/mask

interface (name; default: "") - interface through which the gateway can be reached

routing-mark(name; default: "") - mark of the packet to be mached by this rule. To add a routing mark, use '/ip firewall mangle' commands

src-address(IP address mask) - source IP address/mask table (name; default: "") - routing table, created by user
