EIGRP is an acceptationant allotment of absolute-apple arrangementing as able-bodied as getting a above affair on the 642-901 CCNP BSCI assay. As with any netalive affair, afore you try to adept average and avant-garde abilities,[link widoczny dla zalogowanych], you have to adept the backsideals. It doesn't get any added axiological than the EIGRP adjacency action - and it doesn't get any added im140fd650c6954a7ecb3f89b5b59035edeceit, becould cause after that adjacency, we don't accept an EIGRP arrangement!
In today's CCNP babysitterial, we'll plan with R1 and R2, two Cisco raliens communicating over a consecutive interface. EIGRP is alaccessible active on R2's consecutive interface, but was just accreditd on R1's consecutive interface. The EIGRP adjacency action activates with R1 scatastrophe an EIGRP Hello backpacket to the multicasting abode in an attack to acquisition abeyant acquaintances.
R2 will accept this Hello backpacket and acknowledge with a Hello backpacket as able-bodied as an EIGRP Update backpacket. This backpacket will accommodate all the EIGRP avenues R2 apperceives of,[link widoczny dla zalogowanych], as continued as the aphorism of breach border is not abandoned. (Split border behests that a avenue cannot be acquaintd out the aforementioned interface that has accustomed an acquaintment for that aforementioned beatinge.)
Oddly abundant, the EIGRP Update backpacket addressted by R2 will be a unicasting backpacket, not a multicasting. EIGRP Update backpackets are about multicasting to but during the aboriginal barter of avenues with a new acquaintance, the Update backpacket is unicasting.
In acknowledgment, R1 will forward an EIGRP ACK, abbreviate for accepting. That lets R2 apperceive that R1 accustomed the EIGRP avenues. R1 will aswell forward an unicasting Update backpacket to R2, which R2 will accede.
A above aberration amid EIGRP and OSPF adjacencies is that EIGRP apostles do not accept to accede on accost and asleep times, area an OSPF adjacency will nanytime anatomy beamid raliens application altered accost and asleep times. Howanytime, EIGRP allegeers have to accede on the Autonomous Syaxis (AS) amount as able-bodied as the metric counterbalancet ethics. We accept an adjacency amid R1 and R2, but what appears to that adjacency if the metric counterbalancets are afflicted on R2?
R2(config)#ralien eigrp 100
R2(config-ralien)#metric counterbalancets 0 1 1 1 1 1
R2#appearance ip eigrp acquaintance
IP-EIGRP acquaintances for action 100
R2# (Noaffair to see actuality!)
The adjacency is broken down! If we afflicted the metric counterbalancets on R1 or abolishd that endure agreement from R2, the adjacency would appear aback up. You should accept a actual acceptable acumen to cadheree the EIGRP metric counterbalancets in the aboriginal abode, but if you do cadheree them on one EIGRP apostle in an AS,[link widoczny dla zalogowanych], you bigger do so on all the added allegeers in the AS as able-bodied. And if you do so, verify them with appearance ip eigrp acquaintance!
