Sample OSPF Routing Configuration File

To use any of the dynamic routing protocols with Fireware XTM, you must import or copy and paste a configuration file for the dynamic routing daemon. This topic includes a sample configuration file for the OSPF routing daemon. To use this configuration file as a base for your own configuration file, copy the text into a new text file and save it with a new name. You can then edit the parameters to meet the requirements of your organization.

Optional commands are commented with the "!" character. To enable a command, delete the "!" and modify variables as necessary.

!! SECTION 1: Configure interface properties.
! Set properties for interface eth1.
! interface eth1
!
! Set simple authentication password (SHAREDKEY).
! ip ospf authentication-key SHAREDKEY
!
! Set MD5 authentication key ID (10) and MD5 authentication key (AUTHKEY).
! ip ospf message-digest-key 10 md5 AUTHKEY
!
! Set link cost to 1000 (1-65535) on interface eth1.
! for OSPF link cost table.
! ip ospf cost 1000
!
! Set hello interval to 5 seconds (1-65535); default is 10 seconds.
! ip ospf hello-interval 5
!
! Set dead-interval to 15 seconds (1-65535); default is 40 seconds.
! ip ospf dead-interval 15
!
! Set interval between link-state advertisements (LSA) retransmissions
! to 10 seconds (1-65535); default is 5 seconds.
! ip ospf retransmit-interval 10
!
! Set LSA update interval to 3 seconds (1-3600); default is 1 second.
! ip ospf transmit-delay 3
!
! Set high priority (0-255) to increase eligibility to become the
! designated router (DR).
! ip ospf priority 255

!! SECTION 2: Start OSFP and set daemon properties.
! Enable OSPF daemon. Must be enabled for all OSPF configurations.
! router ospf
!
! Set the router ID manually to 203.0.113.20. If not set, the firewall will
! set its own ID based on an interface IP address.
! ospf router-id 203.0.113.20
!
! Enable RFC 1583 compatibility (increases probability of routing loops).
! ospf rfc1583compatibility
!
! Set area border router (ABR) type to cisco, ibm, shortcut, or standard.
! More information about ABR types is in draft-ietf-ospf-abr-alt-05.txt.
! ospf abr-type cisco
!
! Disable OSPF announcement on interface eth0.
! passive interface eth0
!
! Set global cost to 1000 (0-429495).
! auto-cost reference bandwidth 1000
!
! Set SPF schedule delay to 25 (0-4294967295) seconds and hold time to
! 20 (0-4294967295) seconds; default is 5 and 10 seconds.
! timers spf 25 20

!! SECTION 3: Set network and area properties. Set areas with W.X.Y.Z
!! or Z notation.
! Announce OSPF on network 192.168.253.0/24 network for area 0.0.0.0.
! network 192.168.253.0/24 area 0.0.0.0
!
! Create area 0.0.0.1 and set a classful network range (172.16.254.0/24)
! for the area (range and interface network settings must match).
! area 0.0.0.1 range 172.16.254.0/24
!
! Set virtual link neighbor (172.16.254.1) for area 0.0.0.1.
! area 0.0.0.1 virtual-link 172.16.254.1
!
! Set area 0.0.0.1 as a stub on all routers in area 0.0.0.1.
! area 0.0.0.1 stub
!
! area 0.0.0.2 stub no-summary
!
! Enable simple password authentication for area 0.0.0.0.
! area 0.0.0.0 authentication
!
! Enable MD5 authentication for area 0.0.0.1.
! area 0.0.0.1 authentication message-digest

!! SECTION 4: Redistribute OSPF routes
! Share route of last resort (default route) from kernel routing table
! with OSPF peers.
! default-information originate
!
! Redistribute static routes to OSPF.
! redistribute static
!
! Redistribute routes from all interfaces to OSPF.
! redistribute connected
! redistribute connected route-map
!!Redistribute routes from RIP and BGP to OSPF.
! redistribute rip
! redistribute bgp

!! SECTION 5: Configure route redistribution filters with access lists
!! and route maps.
! Create an access list to only allow redistribution of 10.0.2.0/24.
! access-list LISTNAME permit 10.0.2.0/24
! access-list LISTNAME deny any
!
! Create a route map with name MAPNAME and allow with a
! priority of 10 (1-199).
! route-map MAPNAME permit 10
! match ip address LISTNAME
