Reasons for the fact that the number of default equivalent routes in the routing table is larger than the number of default static routes

3

The reasons for the fact that the number of default equivalent routes in the routing table is larger than the number of default static routes are as follows:
Symptom: Two default equivalent routes are configured.
[sysname] display current-configuration | in ip route ip route-static 0.0.0.0 0.0.0.0 GigabitEthernet1/0/11 42.x.y.1
ip route-static 0.0.0.0 0.0.0.0 GigabitEthernet1/0/10 110.x.y.1
ip route-static 10.0.0.0 255.0.0.0 Eth-Trunk0 10.x.y.249
......
The routing table has three default equivalent routes.
Check whether the following interface is configured with the gateway function:
[sysname] display current-configuration interface ......
#
interface GigabitEthernet1/0/0
alias Cernet
ip address 210.43.47.174 255.255.255.252
service-manage http permit
service-manage https permit
service-manage ping permit
service-manage ssh permit
service-manage snmp permit
service-manage telnet permit
gateway 210.x.y.173
#
......
The gateway command is used to configure the gateway address of the smart routing member interface. By default, the gateway address of the smart routing member interface is invalid. If the interface is used as the smart routing member interface, you must configure the gateway address for it. The firewall delivers the routing entry but does not automatically generate the route configuration command (ip route-static).

Why the number of routes in the OSPF routing table of the OSPF VPN multi-instance is less than the predicted number
In the OSPF VPN multi-instance, loops may occur if PEs and CEs learn BGP and OSPF routes from each other. You can set the DN in Type3, Type5, or Type7 LSAs advertised by PEs to 1 so that CEs ignore the LSAs with the DN value of 1. These LSAs are not used in route calculation, which prevents loops. If the preceding method is used to prevent loops, the number of routes in the OSPF routing table is less than the predicted number. To use the LSAs with DN 1 in route calculation, run the vpn-instance-capability simple command on CEs to disable routing loop detection.

Why is the number of routes in the routing table inconsistent with the number of FIB entries after a required route iteration on an S series switches
Q: Why is the number of routes in the routing table inconsistent with the number of FIB entries after a required route iteration? A: After routes are iterated as required, routes of multiple outbound interfaces are not generated and there is only one route with multiple outbound interfaces. This route is iterated to multiple routes when delivered to the FIB. As a result, the number of routes in the routing table is inconsistent with the number of FIB entries. Among the route flags, R indicates that the route is iterated, and D indicates that the route is successfully delivered to the FIB.

What are priorities of static routes and default routes of the AR router
Default routes can be statically configured or dynamically generated through dynamic routing protocols. If the default route is dynamically generated through dynamic routing protocols, its priority is the same as corresponding protocol. If the default route is statically configured, the default priority is 60, which is similar to that of the static route. Routes comply with the longest mask bit match principle. Specific routes are matched first, and then default routes are matched if the specific routes are not matched.

USG6000 series BGP modified equivalent number of routes
The method for configuring the maximum equivalent route entry for the USG6000 series BGP is as follows. Run the system-view command to enter the system view. Run the bgp as-number command to enter BGP view. Run the ipv4-family unicast command to enter the IPv4 unicast address family view. Run the maximum load-balancing number command to configure the number of BGP load balancing routes. By default, the number of BGP load balancing routes is 1. The maximum number of BGP routes is 8

Default routes of firewalls
Default routes are special routes. Generally, administrators can manually configure default static routes. Default routes can also be generated through dynamic routing protocols, such as OSPF and IS-IS. Default routes are described as follows: To put it in a simple way, default routes are used only when packets to be forwarded do not match any routing entry in a routing table. In a routing table, a default route is the route to network 0.0.0.0 (with the mask 0.0.0.0). You can run the display ip routing-table command to check whether a default route is configured. If the destination address of a packet does not match any entry in the routing table, the packet is sent through a default route. If no default route exists and the destination address of the packet does not match any entry in the routing table, the packet is discarded. An Internet Control Message Protocol (ICMP) packet is then sent, informing the originating host that the destination host or network is unreachable.
