Management Distance in a route

Management Distance definition Management Distance in a route is a method to sort the reliability of the route selection information. The management distance is a certificate between 0 and, and the smaller the value, the higher the credibility. Although the management distance can be set to 1-9, they are reserved for internal use and are not recommended for use. The default Management distance is the default Management Distance for various routing protocols. However, you can manually modify the default Management Distance. Route Selection protocol default Management Distance direct connection interface 0 point to interface static route 0 point to next static Route 1 VPN summary Route 5 external BGP 20 internal VPN 90 IGRP 100 OSPF 110 ISIS 115RIP 120 external Gateway Protocol (EGP) 140 on-demand route selection (ODR) 160 modify the Management Distance of external VPN 170 BGP 200 1. Modify the Management Distance of static routes from ip route 192.168.1.0 255.255.255.0 s1/0 10 2. Modify the Management Distance of the VPN Protocol 1. Modify the default the Management distance between the interior and the exterior of the interior is from the rotuer subnet 100 distance subnet 12 67, the second is the external EIGRP2, and the Management distance for modifying the specific routing of the VPN is the same as that of the router VPN 100 distance 20 0.0.0.0 255.255.255.255 12 20. In the modified AD, 0.0.0.0 255.255.255.255.255 indicates matching any IP address. 12 indicates the access control list. The Access Control List controls the access to a remote network. 3. Modify the Management distance of OSPF routes 1. Modify the default Management distance of OSPF to router ospf area 0 distance ospf inter-area 12 intra-area 12 external 12 inter-area, intra-area indicates the routes between regions, and external indicates the routes outside the region, 2. Modify the Management Distance of the OSPF route. This is similar to the Management Distance syntax used to modify the specific routing of the OSPF route.
