2. Overview Day #1 Maintenance and monitoring Routing protocols Lab Day #2 Introduction to Juniper devices Junos CLI System and interface configuration Lab DAY #4 QoS FHRP Lab DAY #3 Routing policy Firewall filters Lab

3.  FreeBSD (UNIX)  Separate control and forwarding plane  Control plane  Maintains the routing tables, bridging table, and primary forwarding table. (RE)  Forwarding plane  Forwarding packets, rate-limiting, cos, stateless firewall, built on ASICs. (PFE, PIC/PIM, cFEB)  Control and Forwarding plane are connected through an internal link.

5.  Transit and exception traffic  Transit traffic handled solely by PFE. Traffic going only through the router.  Exception traffic is handled by RE.  Packets addressed to the RE (telnet, ssh, pings)  IP packets with option field set  Traffic that requires special processing (ICMP reply messages)

6.  Processes Root> show system processes extensive Last pid: 1527; load averages: 0.26, 0.10, 0.16 up 0+00:12:31 14:17:54 107 processes: 2 running, 87 sleeping, 18 waiting Mem: 144m active, 61m inact, 52m wired, 224m cache, 60m buf, 7512k free Swap: 1024M total, 1024M free Pid username thr pri nice size res state time wcpu command 11 root 1 171 52 0K 12K RUN 10:07 88.18% idle 1313 root 1 96 0 11876K 7956K select 0:01 0.00% snmpd 1315 root 1 4 0 42536K 10720K kqread 0:01 0.00% rpd 1320 root 1 96 0 10256K 4604K select 0:01 0.00% pfed 1343 root 3 20 0 7396K 2472K sigwai 0:09 0.05% jddosd 1494 root 1 96 0 109M 6232K select 0:00 0.00% chassisd

7.  Juniper routers  M-series – Service provider edge, enterprise edge (M-7i, M-320)  J-series – Branch edge (J-2320)  T-series – Service provider core (ie. T-640)  PTX-series – Service provider supercore (ie. PTX5000)  SRX-series – Firewalls (Branch - SRX210, Enterprise SRX1400)  EX-series – L2/L3 switches (ie. EX4200)

9. Initial configuration  Initial login into Juniper router (Amnesiac prompt)  Root and the others  Help topic, reference, appropos  Configure exclusive, private  Login and announcement banners

10. Life of configuration file

12. Users and classes  User can belong to single class  Single class can be assigned to multiple users  Syslog messages

13. IP address and routes  Assign IP address to an interface  Vlan tagging  Protocol independent routing  Aggragete route  Generated route  Static route

14. Primary and preferred address  Primary  Lowest IP address on the interface unless overriden by operator  Only one per interface  Preferred  Lowest IP address of each subnet  One per subnet = One interface can have multiple preferred addresses

15. Protocol independent routing / Static
