I just played with ISIS earlier this week. the clns routing (referenced in
Doyle's book, e.g.) appears to be out of date. It was needed in theory to
support the ATT bit being detected off of L2 routers. Nowadays, it doesn't
appear to be necessary, as I was able to get the default route installed in
an area without it or a static route. HTH!

Do you need to enable clns routing to get ISIS to work. I have seen two
types of configs and this is getting me a little confused.
clns routing
interface ser 1
encap frame
interface ser 1.1 point-to-point
ip address 10.20.20.2 255.255.255.0
ip router isis
clns router isis <---is this needed.
frame-relay interface-dlci 103
router isis
net 49.0001.2222.2222.2222.00
is-type level-2
the above came from cisco
this config below came from a ccie class
interface ser 1
encap fram
ip add 10.20.20.2 255.255.255.0
ip router isis
fram map ip 10.20.20.1 103 broad
fram map clns 10.20.20.1 103 broad
router isis
network 49.0001.2222.2222.2222.00
is type level-2
what does the clns router isis command do, . and do you need to enable clns
routing because the answer sheet I have from the class clns routing is not
in there but the map statements are.
Thanks
Eric
