How to setup syslog server on Linux to receive log messages from Cisco Devices

1. Setup your Cisco devices to send Cisco log to your syslog server

logging 1.2.3.4 ! where 1.2.3.4 is your Cisco log server

logging trap debug

logging on 

2. Make sure rsyslog daemon is installed on your host.  I'm using rsyslog-2.0.2-3.fc8.

3. Tell the syslog daemon to listen for messages from remote devices

vi /etc/sysconfig/rsyslog

SYSLOGD_OPTIONS="-m0 -r" 

4. Tell the rsyslog daemon to write the messages to cisco.log

vi /etc/rsyslog.conf

local7.debug    /var/log/cisco.log

EIGRP – Summarization & Leak-map

EIGRP summarization is configured on interface:

R2(config-if)#int fa0/0

R2(config-if)#ip summary-address eigrp 100 2.2.4.0 255.255.252.0

Before summarization (2.2.4.0/22)

After summarization (2.2.4.0/22)

Leak-map is a features that allows us to advertise a component route (specific route + summary route) that you don’t want to suppressed by manual summarization.

ip summary-address eigrp 100 2.2.4.0 255.255.252.0 5 leak-map LEAKTEST

There are 3 rules to remember:

Rule 1 – Leak-map is configured to reference a route-map that DOES NOT EXIST

Result: Only summary route is advertised.

Rule 2 – Leak-map is configured to reference a route-map and it is referencing to an access-list that DOES NOT EXIST

Result: Summary route + ALL specific routes are advertised.

Rule 3 – Leak-map is configured to reference a route-map and it is referencing to an access-list that exists

Result: Summary route + networks permitted in ACL will be advertised. In this case the summary route + 2.2.5.0/24 permitted in ACL is advertised.
