We want to deny all /32 routes in IGP learned from iBGP.<br>
How can we do this? With a table-map the route go in the IGP:<br>
<br>
<br>
ip prefix-list only32 seq 5 permit <a href="http://0.0.0.0/0" target="_blank">0.0.0.0/0</a> ge 32<br>
<br>
router bgp<br>
 local-as xxxx<br>
 -knip-<br>
<br>
 address-family ipv4 unicast<br>
 table-map deny-blackhole-in-IGP<br>
-knip-<br>
exit-address-family<br>
<br>
<br>
route-map deny-blackhole-in-IGP deny 10<br>
 match ip address prefix-list only32<br>
