Ethernet Secondary Address and ping/Rip

I am trying to do the following:

Ping from R1 to R2 and have R2 learn rip routes via R1

R1--------Ethernet--------R2

Config router 1
interface Ethernet0
 ip address 172.19.35.15 255.255.255.128 secondary
 ip address 192.168.10.33 255.255.255.240
Rip is also configured
IOS Version 12.1(5)T9

Config router 2
interface Ethernet0
 ip address 172.19.35.2 255.255.255.128
Rip is also configured
IOS Version 12.2(1d)

I can ping from router 2 to router 1 no problems. R1 also learns routes from
R2 via rip no problems.

Problem:
I cannot ping from R1 to R2 or to any subnets off of R2. The routes are being
learned via rip but they are not pingable. If I turn on an IP Packet Detail I
get the following output on R2 while pinging from R1
00:42:47: ICMP type=8, code=0
00:42:47: IP: s=172.19.35.2 (local), d=192.168.10.33, len 100, unroutable
00:42:47: ICMP type=0, code=0
00:42:49: IP: s=192.168.10.33 (Ethernet0), d=172.19.35.2 (Ethernet0), len 100,
r
cvd 3
00:42:49: ICMP type=8, code=0
00:42:49: IP: s=172.19.35.2 (local), d=192.168.10.33, len 100, unroutable
00:42:49: ICMP type=0, code=0
00:42:51: IP: s=192.168.10.33 (Ethernet0), d=172.19.35.2 (Ethernet0), len 100,
r
cvd 3
00:42:51: ICMP type=8, code=0
00:42:51: IP: s=172.19.35.2 (local), d=192.168.10.33, len 100, unroutable
00:42:51: ICMP type=0, code=0
00:42:53: IP: s=192.168.10.33 (Ethernet0), d=172.19.35.2 (Ethernet0), len 100,
r
cvd 3

Should this work?

I can make it work by configuring R2 as follows but did not think this was
required
interface Ethernet0
 ip address 172.19.35.2 255.255.255.128 secondary
 ip address 192.168.10.34 255.255.255.240
