CCNA Routing & Switching : EIGRP Configuration

To distribute routing information throughout a network, EIGRP uses non-periodic incremental routing updates. That is, EIGRP only sends routing updates about paths that have changed when those paths change.
The basic problem with sending only routing updates is that you may not know when a path through a neighboring router is no longer available. You can not time out routes, expecting to receive a new routing table from your neighbors. EIGRP relies on neighbor relationships to reliably propagate routing table changes throughout the network; two routers become neighbors when they see each other's hello packets on a common network.
EIGRP sends hello packets every 5 seconds on high bandwidth links and every 60 seconds on low bandwidth multipoint links.
5-second hello:
broadcast media, such as Ethernet, Token Ring, and FDDI
point-to-point serial links, such as PPP or HDLC leased circuits, Frame Relay point-to-point subinterfaces, and ATM point-to-point subinterface
high bandwidth (greater than T1) multipoint circuits, such as ISDN PRI and Frame Relay
60-second hello:
multipoint circuits T1 bandwidth or slower, such as Frame Relay multipoint interfaces, ATM multipoint interfaces, ATM switched virtual circuits, and ISDN BRIs

To remove RIPv2 from your RIPv2 simulation
enable
configure terminal
no router rip
end

Done! You can now setup EIGRP.



Authentication looks like A LOT of work though.
enable
configure terminal
key chain MYCHAINNAME
key 1
key-string eigrppassword
end
configure terminal
interface <Every single EIGRP interface>
ip authentication mode eigrp <AS NUMBER> md5
ip authentication key-chain eigrp <AS NUMBER> MYCHAIN
end

The interface section has to be repeated for every interface I think. :(

Very interested please some more videos 💯💔

[SellaiSuyambuMariAmman]

as u told, for ospf, many routers (like 1800series) used in access layer it might run out of memory and it reboots repeatedly
area concept eliminates this issue

in EIGRP, if we use many routers in access layer, it might run out of memory and it reboots repeatedly. am i right ?
if yes, to eliminate the issue what is the solution?

please respond - NOA solutions
thanks in advance

You seem to be too fast with your lab tutorial.

Are you teaching ? If so, do your activity slowly....don't show your hyper activity to a student who is trying to learn from your video.
