What is default route Cisco?
The default route is a route that a router uses to forward an incoming packet when no other route is available for that packet in the routing table. Routers use the routing table to make the forwarding decision.
Which are the default metrics for this routing protocol?
The Routing Information Protocol (RIP) always uses hop count as the metric. A hop means going through another router. Hop count is the number of routers the router has to go through to get to the destination network. The default maximum hop count in RIP is 15.
How do I set a default route on a Cisco router?
Perform these steps to configure a default route.
- Enter global configuration mode. device# configure terminal.
- Enter 0.0. 0.0 0.0.
- (Optional) Enable the default network route for static route next-hop resolution.
- (Optional) Configure next-hop recursive lookup to resolve the next-hop gateway.
What is a default route in Cisco?
What is AD value of static route and default route?
If it is a static route, the AD-value comes from the “ip route” (or “ipv6 route” ) statement in the configuration (with no AD specified, it will be AD of 1). If it is learned by a routing protocol, the AD value comes from the routing protocol (EIGRP by default 90, ospf by default 110.).
Which three metrics are most commonly used by routing protocols to determine a network path?
The most common metric values are hop, bandwidth, delay, reliability, load, and cost.
What is an IGP and EGP?
An interior gateway protocol (IGP) is a routing protocol that is used to exchange routing information within an autonomous system (AS). In contrast, an Exterior Gateway Protocol (EGP) is for determining network reachability between autonomous systems and makes use of IGPs to resolve routes within an AS.
What is the default route on an IP network?
0.0.0.0/0
The default route in IPv4 is designated as 0.0. 0.0/0 or simply 0/0. Similarly, in IPv6, the default route is specified as ::/0. The subnet mask /0 specifies all networks, and is the shortest match possible.
What happens if the metric is not specified in the route-map?
If the metric is not specified in the route-map, then the metric specified in the redistribute command will be used, and if that is not configured, either, then finally the default-metric command is used. If not even that one is configured, the route may not be redistributed into EIGRP – be cautious about that.
What is the default metric value for static routes?
I see that many router manufactures use metric 0 (ad=1 metric=0 [1/0]) for static routes and also standard mention that non valid metric is -1 and not 0. Rajesh. 06-26-2014 03:37 AM 06-26-2014 03:37 AM Directly connected can be considered as 0 always and static route is with 1 as the default and it differs for each routing protocols.
What is the metric value of the routing protocol?
This is correct because each routing protocol has its own way to calculate metric for example in RIP a metric of 16 is infinite . OSPF intra area routes are 16 bit unsigned integer ( up to 65,535) OSPF inter area are 24 bit values. EIGRP metric was 32 bit in classic EIGRP.
How to set default route value to 0?
06-26-2014 02:17 AM Default route you cannot set it to 0. It can have the metric between 1 to 255. 06-26-2014 03:09 AM 06-26-2014 03:09 AM
