Chapter 7 Configure Switch Features
Route Summarization—Route summarization consolidates and summarizes addresses for an area and is used only with area border routers (ABRs). In OSPF, an ABR advertises
networks in one area into another area. If the network numbers in an area are contiguous, you can configure the ABR to advertise a summary route that covers all individual
networks within the area that are in the specified range. Routing information is condensed at area boundaries. External to the area, one route is advertised for each address range.
OSPF ID Choose an OSPF routing process ID.
Area ID Type the area ID for the routes to be summarized.
IP Address Type the IP address of the summary route.
Netmask Choose a netmask for the summary route.
Advertise Routes Check the checkbox to set the address range status to advertise and generate a Type 3 summary link-state advertisement (LSA).
Authentication—OSPF supports MD5 and clear text neighbor authentication. Use authentication with all routing protocols when possible because route redistribution between
OSPF and other protocols (like RIP) can potentially be used by attackers to subvert routing information.
Interface Name Indicates the name of the OSPF interface.
Authentication Click the authentication type for an interface:
• No Authentication
• Password
• MD5
The authentication type must be the same for all routers and access servers in an area.
Authentication Password Type a shared password to be used by neighboring OSPF routers on a network segment that is using the OSPF simple password authentication.
The password can be any string of keyboard-entered characters up to 8 bytes in length. All neighboring routers on the same network must have
the same password to exchange OSPF information.
MD5 Key ID Type an identifier.
Valid values: 1…255.
MD5 Key Type an alphanumeric password of up to 16 bytes.
Redistribution—Redistributing routes into OSPF from other routing protocols or from static routes causes these routes to become OSPF external routes.
OSPF ID Choose an OSPF routing process ID.
Protocol Click the route type for redistribution into the OSPF routing process:
• Static—-Redistributes static routes into the OSPF routing process.
• Connected—Redistributes connected routes into the OSPF routing process.
• OSPF—Redistributes routes from an OSPF routing process into another OSPF routing process.
• RIP—Redistributes routes from an RIP routing process into the OSPF routing process.
• EIGRP—Redistributes routes from an EIGRP routing process into the OSPF routing process.
Match (Optional). Match and set properties of routes that are imported from OSPF:
• Internal—Matches internal OSPF routes.
• External 1—Matches Type 1 external routes.
• External 2—Matches Type 2 external routes.
• NSSA External 1—Matches Type 1 NSSA routes.
• NSSA External 2—Matches Type 2 NSSA routes.
Metric Value Matches routes with the specified OSPF metric cost value.
Metric Type Matches External Type 1 or 2 routes.
Tag Value Matches routes with the specified name.
Subnets Check the checkbox to include subnetted routes in the redistribution.
Static Neighbor—Define static OSPF neighbors to advertise OSPF routes over a point-to-point, non-broadcast network.
OSPF ID Choose an OSPF routing process ID.
Neighbor Type the IP address of the OSPF neighbor.
