case of multiple rules with the same priority value, the rules that created earlier will take precedence over
the later ones.
If the user does not specify the priority, by default all rules will have same priority value as 1.
IP Standard ACLs and IP Extended ACLs share the same ACL table on the hardware. Hence
priority values need to be configured with the consideration of both IP standard and
extended ACLs.

Creating IP Extended ACLs for IP Traffic
Follow the steps below to create an IP Extended ACL for IP, OSPF or PIM traffic.
Step Command
Description
Step 1 configure terminal
Enters the configuration mode
Step 2 ip access-list extended { <access-list-number(1-
32768)> | <access-list-name> }
Creates an IP Extended ACL using ip-
access-list extended command.
access-list-number – can be any
number from 1 to 32768
access-list-name – can be any name
string up to 32 characters.

Configuresa deny, permitor redirect
ACL rule.
Use the keyword ip to apply this rule to
all IP packets. To apply this rule to only
OSPF or PIM packets, use the keywords
ospf or pimas needed.
The source and destination IP
addresses can be provided with the
keyword host.
The keyword anymay be used to refer
to any IP addresses.
To configure a network IP, address and
mask should be provided.
To apply this rule to packets with
specific TOS values, use the keyword
tos and specify the TOS value to be
matched. User can specify any TOS
values from 0 to 255. The user provided
TOS value will be matched exactly
against the type of service byte on the
IPv4 header of the received
packets.Hence users have to provide
the TOS byte value combining the
precedence and type of service fields of
