Hello, We have upgraded a number of devices to the lastest IOS "c870-advsecurityk9-mz.124-24.T2.bin", and for some reason, the command "peer default ip address" seems broken. interface Dialer1 ip address negotiated ip mtu 1492 ip nat outside no ip virtual-reassembly encapsulation ppp load-interval 30 dialer pool 1 dialer idle-timeout 0 dialer persistent dialer-group 1 peer default ip address 10.10.10.10 no cdp enable ppp authentication pap callin ppp pap sent-username user password 0 password ppp ipcp route default end For reasons too long to explain here, we require in this type of config that the 871/881 device force the use of a particular IP address even if the PPP server reports a different one. This has worked up to and including 124-15.T2.bin. 124-24.T2.bin no longer allows for this, the connection is made but the IP address of the PPP server is missing in the interface. The PPP link is established however no data can be sent or received. The default route is also not installed. With 124-15.T2.bin: Interface User Mode Idle Peer Address Vi1 PPPoE 00:18:42 11.11.11.11 router>show ip route Codes: C - connected, S - static, R - RIP, M - mobile, 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 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route Gateway of last resort is 11.11.11.11 to network 0.0.0.0 66.0.0.0/29 is subnetted, 1 subnets C 66.1.1.88 is directly connected, FastEthernet4 11.0.0.0/32 is subnetted, x subnets C 11.11.11.11 is directly connected, Dialer1 C 11.1.1.88 is directly connected, Dialer1 S* 0.0.0.0/0 [1/0] via 11.11.11.11 With 124-24.T2.bin Line User Host(s) Idle Location * 0 con 0 idle 00:00:00 Interface User Mode Idle Peer Address Vi1 PPPoE 00:00:39 telefax-test#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, 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 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route Gateway of last resort is not set 11.0.0.0/32 is subnetted, 3 subnets C 11.1.1.88 is directly connected, Dialer1 If I remove the peer default IP address, I connect, however the real IP of the PPP server is accepted as the next hop and this is undesireable in this config. I am hoping somebody can tell me this is an oversight and not a permanent "feature"?
