Is there any problem with using ip unnumbered loopback0 on one subinterface and a static IP on another subinterface? I will be using EIGRP. Thanks in advance. The config is as follows:
interface Loopback0
ip address 172.17.0.1 255.255.255.0
no ip directed-broadcast
!
interface Ethernet0
ip address 10.1.1.251 255.255.255.0
no ip directed-broadcast
no ip proxy-arp
!
interface Serial1
no ip address
no ip directed-broadcast
encapsulation frame-relay
no logging event subif-link-status
no logging event dlci-status-change
!
interface Serial1.10 point-to-point
ip address 192.168.253.134 255.255.255.252
no ip directed-broadcast
frame-relay interface-dlci 30
!
interface Serial1.21 point-to-point
ip unnumbered Loopback0
no ip directed-broadcast
shutdown
frame-relay interface-dlci 21
!
router eigrp 2
network 10.0.0.0
