Task 1.1 Tag native vlan

To override the fact that native vlan is not tagged in 802.1q, use the global command :

vlan dot1q native vlan

To not use A trunk even if you need 2 vlan to be used on a link, use voice vlan.

Task 3.5 Default route without any routing protocol

I used DHCP between R9 and BB3 in order to send a gateway.
The protocol used odr.

Task 4.2

R2 will redistribute osfp into BGP but, the redistributed need to only be sent to eBGP neighbor.
I filtered locally generated routes toward iBGP neighbor.

Protocol use another solution :
On redistribution to BGP it set a community for ospf routes. This community is filtered toward iBGP neighbor :

router bgp 245
redi ospf route-map FROMOSPF
neighbor 100.0.0.6 route-map TO6

route-map FROMOSPF
set community 100:100
route-map TO6 deny
match community 1
route-map TO6 permit
ip community-list permit 100:100

Task 4.5 Specific BGP dampening

When setting specific dampening for a route, it should be set with the set dampening command under the route-map and bgp dampeing route-map command.

Task 5.2 SSM

The goal was to permit only one source to ping a group joined on R6 without any filtering.
The solution was on R6 to join a group with a specific sender and use SSM :

ip igmp join-group 236.6.6.6 source 100.0.0.2

As default SSM group is 232.0.0.0/8
the command ip pim ssm range 236.6.6.6 was needed in order to change the default SSM group.

Task 6.1 Dhcp option TFTP

I used tftp option 150 whereas protocol use 66.
66 is the rfc one and allow on tftp server whereas 150 permit more than on address
