Up next is IOS XR and EIGRP
RP/0/7/CPU0:R1#conf t
Thu Mar 29 20:07:53.797 UTC
RP/0/7/CPU0:R1(config)#no router ospf LAB
RP/0/7/CPU0:R1(config)#commit
Once that is deleted, we can now continue with EIGRP configuration.
Just like IOS, we need to give it a process ID
RP/0/7/CPU0:R1(config)#
RP/0/7/CPU0:R1(config)#router eigrp 1
Here is where the difference starts, we need to select the Address family first
RP/0/7/CPU0:R1(config-eigrp)#address-family ipv4
Enter no auto-summary ( this is habitual to be honest )
RP/0/7/CPU0:R1(config-eigrp-af)#no auto-summary
Then assign the interfaces you want in EIGRP
RP/0/7/CPU0:R1(config-eigrp-af)#int l0
RP/0/7/CPU0:R1(config-eigrp-af-if)#int g0/3/0/2
RP/0/7/CPU0:R1(config-eigrp-af-if)#exit
RP/0/7/CPU0:R1(config-eigrp-af)#exit
RP/0/7/CPU0:R1(config-eigrp)#exit
RP/0/7/CPU0:R1(config)#commit
Thu Mar 29 20:08:59.108 UTC
RP/0/7/CPU0:R1(config)#exit
Now lets look at our IP Protocols:
RP/0/7/CPU0:R1#sh ip protocols
Thu Mar 29 20:09:25.058 UTC
Routing Protocol: EIGRP, instance 1
Default context AS: 1, Router ID: 1.1.1.1
Address Family: IPv4
Default networks not flagged in outgoing updates
Default networks not accepted from incoming updates
Distance: internal 90, external 170
Maximum paths: 4
EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0
EIGRP maximum hopcount 100
EIGRP maximum metric variance 1
EIGRP NSF: enabled
NSF-aware route hold timer is 480s
NSF signal timer is 20s
NSF converge timer is 300s
Time since last restart is 00:00:25
SIA Active timer is 180s
Interfaces:
Loopback0
GigabitEthernet0/3/0/2
When you issue the same command under IOS, you have Routing for Networks instead of Interfaces:
R1#sh ip protocols
Routing Protocol is “eigrp 1”
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Default networks flagged in outgoing updates
Default networks accepted from incoming updates
EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0
EIGRP maximum hopcount 100
EIGRP maximum metric variance 1
Redistributing: eigrp 1
EIGRP NSF-aware route hold timer is 240s
Automatic network summarization is not in effect
Maximum path: 4
Routing for Networks:
1.1.1.1/32
150.1.12.0/24
Routing Information Sources:
Gateway Distance Last Update
(this router) 90 00:00:22
150.1.12.2 90 00:00:04
Distance: internal 90 external 170
R1#
Now, let’s look at our routing table on IOS XR.
RP/0/7/CPU0:R1#sh ip route
Thu Mar 29 20:09:31.763 UTC
Codes: C – connected, S – static, R – RIP, B – BGP
D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area
N1 – OSPF NSSA external type 1, N2 – OSPF NSSA external type 2
E1 – OSPF external type 1, E2 – OSPF external type 2, E – EGP
i – ISIS, L1 – IS-IS level-1, L2 – IS-IS level-2
ia – IS-IS inter area, su – IS-IS summary null, * – candidate default
U – per-user static route, o – ODR, L – local, G – DAGR
A – access/subscriber, (!) – FRR Backup path
Gateway of last resort is not set
L 1.1.1.1/32 is directly connected, 00:44:02, Loopback0
D 2.2.2.2/32 [90/130816] via 150.1.12.2, 00:00:11, GigabitEthernet0/3/0/2
C 150.1.12.0/24 is directly connected, 01:30:45, GigabitEthernet0/3/0/2
L 150.1.12.1/32 is directly connected, 01:30:45, GigabitEthernet0/3/0/2
RP/0/7/CPU0:R1#
There, we have a route to R2’s loopback. Lets PING it from our loopback to test connectivity.
RP/0/7/CPU0:R1#ping 2.2.2.2 so l0
Thu Mar 29 20:09:36.232 UTC
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 2/2/5 ms
RP/0/7/CPU0:R1#
And like that basic EIGRP is done.
Now, lets add IPv6 to the EIGRP process.
RP/0/7/CPU0:R1#conf t
Thu Mar 29 20:27:16.966 UTC
RP/0/7/CPU0:R1(config)#router eigrp 1
RP/0/7/CPU0:R1(config-eigrp)#address-family ipv6
RP/0/7/CPU0:R1(config-eigrp-af)#int l0
RP/0/7/CPU0:R1(config-eigrp-af-if)#int g0/3/0/2
RP/0/7/CPU0:R1(config-eigrp-af-if)#commit
Thu Mar 29 20:27:28.352 UTC
RP/0/7/CPU0:R1(config-eigrp-af-if)#
I will be honest here; the correct command to show routes is show route Protocol. Once you add IPv6, you really should to start to use the correct commands. :
RP/0/7/CPU0:R1#sh route ipv6
Thu Mar 29 20:29:31.952 UTC
Codes: C – connected, S – static, R – RIP, B – BGP
D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area

E1 – OSPF external type 1, E2 – OSPF external type 2, E – EGP

ia – IS-IS inter area, su – IS-IS summary null, * – candidate default

L 2001::1/128 is directly connected,

D 2001::2/128
[90/130816] via fe80::2d0:79ff:fe01:3a78, 00:01:43, GigabitEthernet0/3/0/2
C 2001:1:1:12::/64 is directly connected,

L 2001:1:1:12::1/128 is directly connected,
01:02:52, GigabitEthernet0/3/0/2
RP/0/7/CPU0:R1#
Cool – we have an IPv6 route to R2 loopback (2001::2/128)
Lets ping that interface from our loopback interface
RP/0/7/CPU0:R1#ping 2001::2 sou 2001::1
Thu Mar 29 20:31:56.602 UTC
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001::2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 2/4/10 ms
RP/0/7/CPU0:R1#
There you go; we have IPv4 and IPv6 connectivity now.
