EIGRP involves 5 unique sorts of bundle in correspondence with its neighbors. EIGRP bundles are sent with dependable or untrustworthy conveyance and can be sent as a unicast, multicast, or some of the time both. EIGRP parcels type are likewise called EIGRP bundles arrangement or EIGRP messages. The subtleties of the EIGRP bundles are the accompanying:
EIGRP Hello Packets
EIGRP utilizes Hello bundles to find EIGRP-empowered neighbors on straightforwardly associated joins. The switch utilizes hi parcels to perform EIGRP neighbor adjacencies, otherwise called neighbor connections. The welcome parcel is sent as IPv4 and IPv6 multicasts. The bundle is sent utilizing RTP untrustworthy conveyance which isn’t needed an affirmation parcel.
The IPv4 address 224.0.0.10 is held for IPv4 hi bundle multicasting, and IPv6 address FF02::A is saved for IPv6 hi parcel multicasting. On most organizations, EIGRP Hello parcels are sent as multicast bundles at regular intervals. Yet, in certain organizations for instance non-broadcast multi-access organization (NBMA), X.25, Frame Relay, and Asynchronous Transfer Mode (ATM) connects with access connections of T1 (1.544 Mb/s) or more slow, the circumstance of Hello parcels are 60 seconds because of slow speed.
Hi, parcels are likewise used to keep up with recently settled adjacencies. An EIGRP-empowered switch expects that as long as it gets Hello parcels from a neighbor, the neighbor and its courses stay serviceable. EIGRP utilizes a hold clock to decide the greatest time the switch should stand by to get the following Hello prior to proclaiming that neighbor as inaccessible.
The default hold time is multiple times the Hello stretch. Hi stretch for the Ethernet and T1 lines with higher speed is 5 seconds and for more slow speed networks like Non-Broadcast Multi-access networks are 60 seconds. Assuming the hold time terminates, EIGRP announces the course as down and DUAL looks for another way by conveying questions.
EIGRP Update Packets
EIGRP Update Packets are utilized to send steering data. The update Messages are sent both Unicast and Multicast. Update bundles are sent just when required and the updates contain just the directing data required and are sent distinctly to those switches that require it. EIGRP is a distance vector steering convention like RIP, yet it doesn’t send occasional updates like RIP and the course sections don’t lapse. The EIGRP sends refreshes just when changes happen in the organization. The update happens when another organization opens up, a current organization becomes inaccessible, or a change happens in the directing measurement for a current organization.
EIGRP additionally utilizes the terms incomplete and limited for its updates. The term incomplete is utilized to for directing update which incorporates data about the course changes and the term limited alludes to the transmission of halfway updates that are sent uniquely to those switches that the progressions influence. The halfway and limited update limits the data transfer capacity that is expected to send EIGRP refreshes.
EIGRP engenders directing data to EIGRP neighbors’ uses dependable conveyance, and that implies the sending switch should require an affirmation. An update parcel is shipped off another neighbor as unicast. On the off chance that this update is connected with any course change, it is sent as Multicast.
EIGRP Acknowledgment Packets
EIGRP Acknowledgment Packets are utilized as a criticism to the Update, Query or Reply bundles as an input component. It isn’t utilized for Hello Packets and Acknowledgment Packets. It is a vacant welcome messages with next to no information and they are sent as untrustworthy unicast.
EIGRP Query Packets
EIGRP Query Packets ask and demand for any directing update. Assuming a replacement falls flat, with Query messages, a reinforcement course is inquired. EIGRP questions utilize dependable conveyance as a unicast or multicast message. Whenever a switch lost availability then it conveys questions to all EIGRP neighbors looking for any potential courses to the LAN. Because of dependable conveyance, the getting switch should return an EIGRP affirmation. The affirmation educates the shipper regarding about the question gathering.
EIGRP Reply Packets
EIGRP Reply Packets are utilized as a reaction to the Query Packets including the backup ways to go to the mentioned objective. It is sent with solid conveyance as unicast messages.
