tại sao frame-relay map table có địa chỉ 0.0.0.0?

[anhtt72]

Cho tôi hỏi vì sao lại có các ip 0.0.0.0 trong lệnh show frame-relay map sau.

R2#show frame-relay map
Serial0/0 (up): ip 0.0.0.0 dlci 244(0xF4,0x3C40)
broadcast,
CISCO, status defined, active
Serial0/0 (up): ip 0.0.0.0 dlci 233(0xE9,0x3890)
broadcast,
CISCO, status defined, active
Serial0/0 (up): ip 0.0.0.0 dlci 221(0xDD,0x34D0)
broadcast,
CISCO, status defined, active
Serial0/0.234 (up): ip 172.16.234.3 dlci 233(0xE9,0x3890), dynamic,
broadcast,, status defined, active

config như sau:

interface Serial0/0
no ip address
encapsulation frame-relay
frame-relay lmi-type cisco
!
interface Serial0/0.234 multipoint
ip address 172.16.234.2 255.255.255.248
ip ospf network broadcast
ip ospf priority 0
frame-relay interface-dlci 233

sau khi reload router thì chỉ còn
R2#show frame-relay map
Serial0/0.234 (up): ip 172.16.234.3 dlci 233(0xE9,0x3890), dynamic,
broadcast,, status defined, active


Cảm ơn nhiều.
Anh

nếu các dòng trên mất đi ngay từ đầu và không cần reload, cách làm nên là


interface Serial0/0
no ip address
encapsulation frame-relay
frame-relay lmi-type cisco
no frame-relay inverse-arp
no arp frame-relay
no shut <<<<--------làm sau cùng
!
interface Serial0/0.234 multipoint
ip address 172.16.234.2 255.255.255.248
ip ospf network broadcast
ip ospf priority 0
frame-relay interface-dlci 233
no shut <<<<<<-----------làm sau cùng
