- OSPF CCNA CCNP Workbook Lab1 - Cisco Learning Network
Task 2 (Area 0) · Configure OSPFv2 in R1 and R2 in area 0 using process id 100 · R1 should use router id 0 0 0 1 · R2 should use the highest Virtual interface IP address as router id · R1 should use Network command to enable OSPF in G0 1 interface · R2 should not use Network command to enable OSPF in G0 1, loopback 2 and loopback22 interfaces · R2 loopback2 interface should be treated as
- ASBR vs ABR - Cisco Learning Network
OSPF uses an hierarchical structure that divides the AS in areas,Area 0 is the backbone and MUST always exists, all other areas connect to area 0 Traffic between areas must pass through area 0 A router that connects area 0 to any other area is known as ABR (area border router)
- OSPF: Why use Loopback over Router-ID - Cisco Learning Network
•If OSPF router ID needs to be routable, configure a loopback interface with the same IP address and include it under the OSPF process •If applications like DLSW+, IPSec, etc , require optimal routing, configure separate loopback interface (s) and use IP addresses from a different address space which is not summarized at the ABRs
- OSPF not showing neighbor relationships. - Cisco Learning Network
OSPF sends out hello messages to neighboring routers to announce itself as an OSPF router and discover who its neighbor routers are Routers have to agree on certain parameters (such as timers and being on a common subnet) before they can become neighbors
- default-information-originate always - Cisco Learning Network
The "default-information orginate" command used on a router running ospf allows it advertise the default route to the ospf domain (if a default route exixts on it's routing table)
- Advertising loopback network as 24 instead of 32 in OSPF?
In Cisco IOS Software Releases 11 3T and 12 0, if the ip ospf network point-to-point command is configured under loopbacks, OSPF advertises the loopback subnet as the actual subnet configured on loopbacks ISDN dialer interface advertises 32 subnet instead of its configured subnet mask
- passive interface in OSPF - Cisco Learning Network
passive interface in OSPF ? Hi, I am having difficulty in understanding the benefit of using the passive interface command under OSPF The scenario is from Chapter 4 of the CCNP Route Manual Lab 4-1 "Redistribution between RIP and OSPF"
