packet tracker assignment Routers are ISR$4331$ with added Serial interface cards, switches are $2960,$ servers are $($End devices $->$ Server$)$ OSPF R$1,$ R$2$ and R $3-$ Create the hostname, and an enable secret password of 'vector'. $-$ Create the IP addresses on the interfaces. $-$ Create OSPF process $\text{'}1\text{'}$ on all routers. Create Router ID's as follows, R$1-1\mathrm{.}1\mathrm{.}1\mathrm{.}1,$ R$2-2\mathrm{.}2\mathrm{.}2\mathrm{.}2$ and R$3-3\mathrm{.}3\mathrm{.}3\mathrm{.}3-$ Put the active interfaces on the three routers in the OSPF process $1$ area $0,$ by going under each interface and applying the command $($not the network command$).$ Tuning OSPF Cost Can PC$-$A ping Server$-$A$?$ From PA$-$A run a tracert to Server$-$A$.$ Currently the route goes via R$1$ to R$3.$ We want to modify the network so that the traffic goes from PC$-$A to R$1$ to R$2$ to R$3$ to Server$-$A$.$ Use the ospf cost command and set the cost $=10$ on the links from R$1$ to R$2,$ and from R$2$ to R$3.($both ends of each link need to be modified. The initial costs should have been $64,$ and we are changing them to $10)$ We need to then clear the ospf processes on all $3$ routers. Now that the process has re$-$converved, run the tracert again and confirm that the traffic goes via R $2.$ ACL's Extended On both servers, go to 'Services $->$ HTTP$\text{'}$ and ensure that HTTP is turned on$.$ Ensure that both PC$-$A and PC$-$B can HTTP into both servers. Create an Extended ACL on R$1$ that will $-$ Allow all traffic from PC$-$A to anywhere $-$ Deny HTTP traffic from PC$-$B to Server$-$B $-$ Allow all other PC$-$B traffic to anywhere $-$ Reminder that this should be put as close to the source as possible. Standard We want to SSH into R$3.$ On R$3$ create a username $=$ admin, password$=$ cisco, domainname $=$ www$.$vti.edu, and generate SSH keys with modulus$=1024.$ Vty lines $0$ to $4$ should allow ssh only, using the local database for login$.$ Create a standard ACL to allow only PC$-$A to be able to SSH into the router, and apply the ACL correctly. Confirm that only PC$-$A can SSH into R$3$ Save your configurations, save the file, and email.
