Command : Passive Interface in RIP, EIGRP & OSPF

Passive-interface command is used in all routing protocols to disable sending updates out from a specific interface. However the command behavior varies from o­ne protocol to another.

In RIP: this command will disable sending multicast updates via a specific interface but will allow listening to incoming updates from other RIP speaking neighbors.

[Simply router can able to receive updates o­n that passive interface and use them in the routing table but it will never sends any update through that specific interface.]

In EIGRP: this command stops sending outgoing hello packets, hence the router can not form any neighbor relationship via the passive interface. [Simply it will never send & receive any routing updates to neighbors.]

In OSPF the passive-interface has a similar behavior to EIGRP. The command suppresses hello packets and hence neighbor relationships.

Note : Incase of any suggestion,pls let us know...

Cisco Routers Configuration registers Value

Cisco Routers Configuration registers Value

************************************

• The configuration register is a 16 bit (2 Byte) value
• The value range is from 0x0 to 0xFFFF.
• 0x2102 is the factory-default configuration register value.
• 0x2142 boots from flash without using NVRAM contents good for password recovery.
• 0x2101 boots from boot prom image not flash, good for upgrading image on flash.
• 0x2141 boots from boot prom and ignores NVRAM contents.
• 0x141, which disables the Break key, ignores the NVRAM configuration, and
  boots the default system image from ROM.
