Metric is based off of |
Bandwidth and delay |
|

Change in topology only |
|
Set bandwidth and delay |
Interface config bandwidth and delay commands |

|
Unit of measurement for delay command |
tens of microseconds |
|
Default serial line BW and delay |
BW: 1544, delay: 20,000 |
|
Feasible distance |
Calculated on LOCAL router for best route to subnet |
|
Reported distance |
Calculated on NEXT-HOP router for best route to subnet |
|
Name for best route to subnet |
Successor |
|
Alternative immediately available route to subnet |
Feasible successor |
|
Criteria to be feasible successor |
Second best metric.. Reported distance must be lower than feasible distance of successor |
|
Algorithm used to find a route when route fails with no feasible successor |
DUAL - Diffusing Update Algorithm |
|
Triggered update |
Routing protocol feature where RP does not wait for next periodic update, immediately sends update when a change in network |
|
Set interface hello and hold time (IPv4) |
Interface config ip hello-interval eigrp asn ip hold-time eigrp asn |
|
Show commands for EIGRP enabled interfaces IPv4 |
show ip eigrp interface [detail] show ip protocols |
|
Show commands for EIGRP neighbors IPv4 |
show ip protocols show ip eigrp neighbors [type number] |
|
Show commands for EIGRP topology IPv4 |
show ip eigrp topology [subnet/prefix] |
|
Show commands for EIGRP routes IPv4 |
show ip route eigrp |
|
Show command to see hello/hold on an interface IPv4 |
show ip eigrp interfaces detail [type] |
|
show command to see router ID IPv4 |
show ip protocols |
|
3 ways EIGRP gets router ID |
1. eigrp router id 1.1.1.1 subcommand 2. Highest IP address of Loopback addresses 3. Highest IP of other up/up interfaces |
|
sh ip route AD and code for EIGRP |
AD: 90 Code: D |
|
Show command to see FD/RD of successor and feasible successor IPv4 |
show ip eigrp topology |
|
Show command to examine metric components for a given subnet IPv4 |
show ip eigrp topology 10.1.3.0/24 |
|
Change maximum paths to 4 for load balancing |
EIGRP config mode maximum-paths 4 |
|
Variance command range |
1-128 |
|
Achieving unequal cost load balancing |
Use variance command |
|
variance 2 with a successor FD 50 and RD 30 will allow a route with a maximum [?? FD/RD] of ?? to be added to the router table |
FD - 100 |
|
Discontiguous network |
Classful network separated by another classful network |
|
Command to disable auto summarization |
no auto-summary EIGRP subcommand |
|
Neighbor table shows address of.. |
Working neighbor
Neighbor's interface IP address |
|
Show command to see passive interfaces IPv4
|
show ip protocols | begin Routing for networks |
|
IPv6 command to enable EIGRP on an interface |
ipv6 eigrp 1 |
|
Command to set router ID |
eigrp router-id 1.1.1.1 |
|
Change hello interval and hold time for IPv6 |
ipv6 hello-interval eigrp (AS) (time) ipv6 hold-time eigrp (as) (time) |
|
IPv6 show EIGRP interfaces and marks passive |
show ipv6 protocols |
|
Address shown with show ipv6 eigrp neighbors command |
link local address |
|
2 metric components that can optionally be used |
Reliability, load |
|
