Situation in which an outbound interface is specified for the static route of the firewall

1

Note the following when specifying the outbound interface for the static route of a firewall:

1. For the point-to-point interface, if you specify the outbound interface, it is considered that the next-hop address is specified, that is, the peer interface address. If the Point-to-Point Protocol (PPP) is encapsulated for the POS, the peer IP address is obtained through PPP negotiation. In this situation, you only need to specify the outbound interface instead of the next-hop address.

2. Non Broadcast Multiple Access (NBMA) interfaces (such as ATM interfaces) support the point-to-multipoint network. In this situation, in addition to the IP route, you need to map the IP address with the link-layer address on the link layer. You must configure the next-hop IP address.

3. If you set the broadcast interface (such as the Ethernet interface) and virtual-template (VT) interface as the outbound interfaces when configuring the static route, you must specify the next-hop address. Because the Ethernet interface is a broadcast interface and the VT interface is associated with multiple virtual access interfaces, multiple next hops exist. The next hop cannot be identified. In the application, you must specify the broadcast interface (such as the Ethernet interface) or VT interface as the outbound interface. You are suggested to specify the next-hop address corresponding to the outbound interface.

Composition of the static route on a firewall
On the firewall, run the ip route-static command to configure a static route, including: -Destination address and mask -Outbound interface and next-hop address

Can the next hop address be not specified in a static route
You must specify the next hop address in a static route, but you can choose not to specify the outbound interface. The ip route-static ip-address mask Vlanif vlan-id command specifies the VLANIF interface as the outbound interface in a static route and does not specify the next hop address. This command is not recommended because it does not take effect and lowers device performance.

Can I specify an outbound interface for the circular DCC
Yes. To specify an outbound interface, run the dialer route ip next-hop-address [ user hostname | broadcast ] * [ dial-string [ autodial | interface interface-type interface-number ] * ] command.
