USG configures the ospf type

4

The USG2000 & 5000 & 6000 configuration type method is as follows
1. Run: system-view The system view is displayed.

2. Run: interface interface-type interface-number The interface view is displayed.

3. Run the ospf network-type {broadcast | nbma | p2mp | p2p} command to configure the network type of the OSPF interface.

When the user configures a new network type for the interface, the network type of the original interface will be replaced.

The USG configures the OSPF link cost method
The USG2000 & 5000 & 6000 configures the OSPF link cost as follows: 1. Run: system-view The system view is displayed. 2. Run: interface interface-type interface-number The interface view is displayed. 3. Run the ospf cost cost command to set the cost of the OSPF interface. The OSPF protocol cost of the interface is valid for the OSPF route learned from the interface. That is, the cost of the route generated in the device routing table is equal to the cost of the route advertised by the interface. The cost of the interface is set by the ospf cost command.

Configuring the OSPF priority on the firewall
The method for modifying the OSPF priority on the USG2000&5000&6000 is as follows: -Modifying the OSPF priority: [USG]ospf [USG-ospf-1]preference 30

Can the OSPF network type be configured as P2P or NBMA
This configuration, however, is not recommended unless necessary or you are aware of the consequences of modifying the default network type. A beginner may believe that the broadcast and P2P networks in OSPF must also be broadcast or P2P at the link layer. Actually, the OSPF network type is independent of the physical media and link layer protocol.

Common LSA types of OSPF
Common LSA types of OSPF are as follows: Type 1 LSA: router LSA. Generated by each router, describes the router's link status and cost, and advertised within the area to which it belongs. Type 2 LSA: network LSA. Describes the link status of all routers on the local network segment. Network-LSAs are generated by a designated router (DR) and advertised within the area to which the DR belongs. Type 3 LSA: summary LSA. Generated by ABR, describes all routes in the area, and advertised to other relevant areas. Type 4 LSA: ASBR-summary LSA. An ASBR-summary-LSA describes routes to the ASBR in an area. The routes are advertised to all areas except the area to which the ASBR belongs. Type 5 LSA: AS-external-LSA. Describes AS external routes, which are advertised to all areas except stub areas and NSSAs. AS-external-LSAs are generated by an ASBR. Type 7 LSA: NSSA AS-external-LSA. Describes AS external routes. NSSA-LSAs are generated by an ASBR and advertised only within NSSAs. The original OSPF packet coding is not Type Length Value (TLV)-based. For the extension of OSPF functions, only the LSA types of OSPF can be extended. Type 6 LSAs are Group-Membership-LSAs used to identify multicast group membership in the Multicast Open Shortest Path First (MOSPF) protocol. Type 6 LSAs are not supported on the firewall. Type 8 LSAs are External-Attributes-LSAs used to redistribute Border Gateway Protocol (BGP) routes into OSPF and reserve the BGP autonomous system (AS) path information. Type 8 LSAs are not supported on the firewall. RFC 2370 defines an important LSA type, namely, Opaque LSA, which allows for TLV-like structures. OSPF applications, such as OSPF traffic engineering, are based on the Opaque LSA extension abilities: Type 9 LSAs are Opaque LSAs that are advertised within the local link only; Type 10 LSAs are Opaque LSAs that are advertised within the local area only; Type 11 LSAs, similar to Type 5 LSAs, are Opaque LSAs that are advertised within the local AS.
