Comparative 1.ospf:
1) Huawei:
ospf basic configuration:
The system tried: setting router-id: router id id router
system attempts: attempting to enter the configuration ospf: ospf
entry region arranged tried: area ID area
interface ospf added network: Network anti-segment code
returns a user attempts: return
2) Cisco:
The ospf command:
enable ospf process: global configuration mode: router ospf process ID
to set router-id: ospf configuration mode: router-id ip address (such as 1.1.1.1)
set directly connected network segment: OSPF distribution pattern: net local area network address inverted area number
routing table: privileged mode: sh ip ro (o represents the beginning of the OSPF routing learned)
2.ospf virtual link configuration:
1) Huawei:
[R2] OSPF
[OSPF--R2. 1] area zone number
[R2-ospf-1-area -0.0.0.2] vlink-peer partner's router-id ## ABR virtual link configuration
2) Cisco:
the OSPF virtual link :
(. 1) the OSPF virtual link: refers to a non-backbone through a link to the region of the connection (channel) backbone region;
(2) the OSPF virtual links requirement:
not at the tip region;
virtual link must be configured in two ABR between;
virtual link stability Depending on its stability through the region;
In addition to the non-connected virtual link to the backbone area backbone region also helps to provide the logically redundant (backup).
(3) a virtual link (virtual-link) configuration command: router-id area other vir region number of ABR
3. peripheral areas:
1) and the distal region distal region completely:
effects: reduce LSA entries within the routing area and the entry; ABR automatically generates a default route to publish the distal tip area and completely.
Note: conditions are met
only a default route as a regional export (stub network);
area can not be used as a virtual link across the region;
no ASBR into the stub area;
not the backbone area area 0.
2) Cisco disposed distal and fully distal region:
peripheral zone: area area number stub
completely tip area: area area number stub NO-Summary
the NSSA (impure peripheral region) zone configuration: area area number NSSA NO-Summary;
. 3) Huawei:
tip area: area area number -> stub
fully distal area: area area number -> stub no-summary
impure completely tip region: area area number -> nssa no-summary
non stubby area: area area number - > nssa
Note: regional advantages NSSA: reserved advantages distal region, and supports non-ASBR stub networks within the region;
4. Route redistribution:
1) Cisco Configuration Routing redistribution:
RIP to redistribute OSPF: redis ospf process ID metric 10 (metric measure, rip to measure the number of hops)
OSPF to redistribute RIP: RIP Metric 200 Redis the subnets
OSPF to redistribute static : 100 Redis the subnets Metric Metric static-type 2 (O E2 of)
the OSPF redistribute default: 10 Metric Metric DEF-type orig. 1 (E1 O)
2) Huawei:
injecting static route into ospf: ospf -> import-route static
injection default route to OSPF: OSPF -> default-route-advertise Always
rip injected into OSPF: OSPF -> Import-route rip. 1
OSPF injected into rip: rip -> import-route ospf 1 cost 10
is injected into the default route rip : rip -> default-route originate
Note: the role of routing redistribution of routing mutual learning between different AS (autonomous system), all operations must be redistributed ASBR (border routes.)
