Cisco asa default route metric. In this case, the router adds Mar 4, 2025 · The ASA implements static route tracking by associating a static route with a monitoring target host on the destination network that the ASA monitors using ICMP echo requests. To route traffic to a nonconnected host or network, you must define a static route to the host or network or, at a minimum, a default route for any networks to which the ASA is not directly connected; for example, when there is a router between a network and the ASA. Routes in the routing table include a metric called "administrative distance" that provides a relative priority to a given route. The Routing Table and Route Selection When NAT translations (xlates) and rules do not determine the egress interface, the system uses the routing table to determine the path for a packet. The hosts pointing to the default route with metric 1 are able to access the internet to and fro,however the hosts pointing to default route with metric 2 are accessible from public internet but not from inside. Jun 25, 2014 · A static route does not have a metric unless it is being redistributed into a dynamic routing protocol and in that case the assignment of metric is dependent on the particular routing protocol (OSPF does it differently from EIGRP which does it differently from RIP). Oct 6, 2011 · As Varun said the ASA is going to send the traffic through the interface with the lowest metric value, eventhough the route goes down it is not going to be taken out from the routing table of the ASA so there is nothing much you can do with that, unless you configure SLA monitoring that will let you monitor these default routes and change the en Oct 15, 2020 · You are using a route map to set metric (MED) for prefixes that you advertise to them, so that they will have a primary path and a backup path for how they send traffic to you. Jun 16, 2014 · To route traffic to a nonconnected host or network, you must define a static route to the host or network or, at a minimum, a default route for any networks to which the ASA is not directly connected; for example, when there is a router between a network and the ASA. If an echo reply is not received within a specified time period, the host is considered down, and the associated route is removed from the routing table. Apr 6, 2020 · The smaller the administrative distance value, the more preference is given to the protocol. It does appear that the prefixes that they advertise to you are sent with equal attributes. For example, if the ASA receives a route to a certain network from both an OSPF routing process (default administrative distance - 110) and a RIP routing process (default administrative distance - 120), the ASA chooses the OSPF route because OSPF has a higher preference. About Route Maps Guidelines for Route Maps Define a Route Map Customize a Route Map Example for Route Maps History for Route Maps About Route Maps Route maps are used when redistributing routes into an OSPF, RIP, EIGRP or BGP routing process. Nov 1, 2013 · I have a "simple" question regarding static routing on an ASA 5510 and metrics. I just want to confirm that if I add the following configuration that the Route 1 will take precedence over Route 2 due to the metric value being lower. I think we can assume that this is working correctly. In this case, the router adds . Apr 2, 2025 · This chapter describes how to configure and customize route-maps, for ASA. They are also used when generating a default route into an OSPF routing The metric value of the static routes is 0, and it will not change if you set the static route with the next hop or the exit interface, in both cases the metric will be 0 and the AD will be 1 for both of them. Jul 28, 2025 · The smaller the administrative distance value, the more preference is given to the protocol. Mar 15, 2009 · I suggested to use 1 port of the ASA, plug it in a switch and connect its corresponding 2 routers in the same switch then, to use 2 route commands on the ASA with 2 different metrics ( 10, 200 ) , the 10 for the main and the 200 for the backup. kmi rstcfjy udbygk opo nglxgv vvbcj rwxcl qmdjdvt gagf xduab
