Hi,
With following config R2 acts as PPPoE server (R2 assign an IP address to a PPPoE client via DHCP)
ip dhcp excluded-address 10.10.1.2 10.10.1.254
!
ip dhcp pool R1
network 10.10.1.0 255.255.255.0
!
bba-group pppoe global
virtual-template 2
!
!
interface FastEthernet0/0
no ip address
ip virtual-reassembly
duplex auto
speed auto
pppoe enable group global
!
!
interface Virtual-Template2
ip address 10.10.1.2 255.255.255.0
no peer default ip address
!
On R2 when PPP session go up a virtual-access interface is cloned form virtual-template:
R2#sh ip int brie
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES NVRAM up up
FastEthernet0/1 10.10.2.2 YES NVRAM up up
Virtual-Access1 unassigned YES unset up up
Virtual-Access1.1 10.10.1.2 YES TFTP up up <---------
Virtual-Access2 unassigned YES unset down down
Virtual-Template2 10.10.1.2 YES NVRAM down down
Now I can ping the remote side (PPPoE client) but not the local interface (10.10.1.2)
R2#deb ip pack det
IP packet debugging is on (detailed)
R2#
R2#
R2#ping 10.10.1.2 re 2
Type escape sequence to abort.
Sending 2, 100-byte ICMP Echos to 10.10.1.2, timeout is 2 seconds:
*Mar 1 00:05:36.531: IP: tableid=0, s=10.10.1.2 (local), d=10.10.1.2 (Virtual-Access1.1), routed via RIB
*Mar 1 00:05:36.535: IP: s=10.10.1.2 (local), d=10.10.1.2 (Virtual-Access1.1), len 100, sending
*Mar 1 00:05:36.539: ICMP type=8, code=0

Success rate is 0 percent (0/2)
R2#
from debug it seems R2 originates ICMP echo, route the packet to virtual-access1.1 and then this (sw) interface send it...
I've checked on the remote side....ICMP echoes are not received (as instead when pinging the local IP address configured on a serial interface...)
Why this behaviour ? Thanks.
