This is because router7 does not have a route to the primary address on
R6_E0
As far as R6 is concerned 172.16.136.0 and 10.2.6.0/23 are out of E0.
When you generate an ICMP ECHO from R6, the source IP address is
172.16.136.6
This ECHO request is processes by R7, but it doesn't have a route back.
Try two things. (separately)
1. do an extended ping from R6 and force the source ip address to be
10.2.6.6
2. add a route on R7 to 172.16.136.0 - out of E0 would do

Subject: Can ping to a 2ndary addr but not from 2ndary addr
Hi,
This seems very strange to me.
I have 2 routers R6 and R7 connected via a Cat5k Ethernet. Both routers int
E0 are in vlan 2,
R7 config:
int e0
ip addr 10.2.6.7 255.255.254.0
R6 config:
int E0
ip addr 10.2.6.6 255.255.254.0 secondary
ip addr 172.16.136.6 255.255.255.0
The route table of both routers shows an entry for 10.2.6.0/23 and both int
are up up when I do a show int e0.
From R7 I can ping 10.2.6.6 but from R6 I can't ping 10.2.6.7
Can anybody explain why this is and what I should about it?
I'd very much would appreciate it. Thanks, Raj
