Hi,
I'm studing for BGP certification and I've just read a document found on Cisco site
 related to sessions and policy templates named "BGP Configuration Using Peer Templates"
http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/s_bgpct.html

I hope you can clarify/confirm the logic behind the above examples:

-In example1: are sequence numbers in "template peer-policy CUSTOMER-A"
used to excecute the template GLOBAL first? If yes, this means that weight 
 2345 will overwrite 1000 right?. What's about the prefix list? Both "no-martian" and 
"ALLOW-PRIMARY-A" are considered or the last prefix will overwrite the first? In case 
they are overwritten, does this happen even if the prefix lists are apllied in different
direction?

-In example 2: It seems that seq# are used with a different meaning here, but are they 
really necessary?

Thank in advance.

Marco




==========================
EXAMPLE 1

router bgp 101
 template peer-policy GLOBAL
  prefix-list no-martian in
  weight 1000
  maximum-prefix 10000
  send-community
 exit-peer-policy
 !
 template peer-policy PRIMARY-IN
  route-map SET-LOCAL in
  prefix-list ALLOW-PRIMARY-A in
  default-originate
  weight 2345
 exit-peer-policy
 !
 template peer-policy CUSTOMER-A
  route-map SET-COMMUNITY in
  filter-list 20 in
  inherit peer-policy PRIMARY-IN 20	!!Note the use of seq# here
  inherit peer-policy GLOBAL 10		!!Note the use of seq# here
 exit-peer-policy
 !
 bgp log-neighbor-changes
 neighbor 10.0.0.1 remote-as 202
 neighbor 10.0.0.1 inherit peer-policy CUSTOMER-A


======================

EXAMPLE 2
template peer-policy POLICY-TEMPLATE-ONE 10	!!Note the use of seq# here
  weight 1000
 exit peer-policy
template peer-policy POLICY-TEMPLATE-TWO 20	!!Note the use of seq# here
  inherit peer-policy POLICY-TEMPLATE-ONE
  weight 2000
 exit peer-policy
Template peer-policy POLICY-TEMPLATE-THREE 30	!!Note the use of seq# here
  inherit peer-policy POLICY-TEMPLATE-TWO
  weight 3000
 exit peer-policy
