Eigrp router id configuration for 2 difference eigrp process id routing redistribution

Hi All,

   I need to setup a router configured with eigrp process id 2 on WAN interface and Internal LAN interface configured with Eigrp process id 1. since they are running in difference process id, i need to configure mutual redistribution between process id 1 and process id 2 in order for outside WAN network to talk to inside LAN network.

But I am confused with the process eigrp process id configuration. Can i configure the same router id into 2 difference eigrp process id and redistribute them to each other ? or i should configure 2 loopback interface, assigned one of the loopback ip to process id 1 as eigrp router id and another loopback interface assigned as eigrp router id for eigrp process id 2? will it cause any issue or make any difference?

Thanks a lots for the reply in advanced

Option 1:

interface loopback 0

ip address 172.16.16.1

router eigrp 1

network 10.1.1.0 0.0.0.255

no auto-summary

eigrp router-id 172.16.16.1

redistribute eigrp 2

router eigrp 2

network 192.168.1 0.0.0.255

no auto-summary

eigrp router-id 172.16.16.1

redistribute eigrp 1

Option 2:

interface loopback 0

ip address 172.16.16.1

interface loopback 0

ip address 172.16.16.2

router eigrp 1

network 10.1.1.0 0.0.0.255

no auto-summary

eigrp router-id 172.16.16.1

redistribute eigrp 2

router eigrp 2

network 192.168.1 0.0.0.255

no auto-summary

eigrp router-id 172.16.16.2

redistribute eigrp 1
